キャット・スティーヴンス
In October 2004 the British newspapers The Sun and The Sunday Times voiced their support for Yusuf Islam's deportation by the U.S. government, claiming that he had supported terrorism. Yusuf Islam sued for libel and received a substantial out-of-court "agreed settlement" and apologies from the newspapers. Both newspapers acknowledged that Yusuf Islam has never supported terrorism and that, to the contrary, he had recently been given a Man of Peace award from the private Nobel Peace Prize Laureates Committee.
Yusuf Islam responded that he was "...delighted by the settlement [which] helps vindicate my character and good name.... It seems to be the easiest thing in the world these days to make scurrilous accusations against Muslims, and in my case it directly impacts on my relief work and damages my reputation as an artist. The harm done is often difficult to repair", and added that he intended to donate the financial award given to him by the court to help orphans of the tsunami in the Indian Ocean.
Yusuf Islam wrote about the experience in a newspaper article titled "A Cat in a Wild World".
For several years during the 1990s, Yusuf Islam made recordings featuring lyrics about Islamic themes accompanied only by basic percussion instruments, which he felt were acceptable to his faith. In the late 1990s, he was featured as a guest singer of "God Is the Light" on an album by the Nasheed group, Raihan.
He produced a children's album  in 2000 called A Is for Allah after realizing there were few materials designed to educate children about Islam. He also established the record label called Mountain of Light Productions, which donates a percentage of its proceeds to Islam's Small Kindness charity.
On the occasion of the 2000 re-release of his Cat Stevens albums, Yusuf explained that he had stopped performing in English due to his misunderstanding of the Islamic faith. "This issue of music in Islam is not as cut-and-dried as I was led to believe . . . I relied on heresy (sic), that was perhaps my mistake."
In 2003, after repeated encouragement from within the Muslim world, Yusuf Islam once again recorded "Peace Train" for a compilation CD, which also included performances by David Bowie and Paul McCartney. He performed "Wild World" in Nelson Mandela's 46664 concert with his former session player Peter Gabriel, the first time he had publicly performed in English in 25 years. In December 2004, he and Ronan Keating released a new version of "Father and Son" that debuted at number two, behind Band Aid 20's "Do They Know It's Christmas?". The proceeds of "Father and Son" were donated to the Band Aid charity. Keating's former group, Boyzone, had a hit with the song a decade earlier.
In a 2005 press release, he explains his revived recording career:
After I embraced Islam many people told me to carry on composing and recording but at the time I was hesitant for fear that it might be for the wrong reasons. I felt unsure what the right course of action was. I guess it is only now after all these years that I've come to fully understand and appreciate what everyone has been asking of me. It's as if I've come full circle - however, I have gathered a lot of knowledge on the subject in the meantime.
In early 2005, Yusuf Islam released a new song entitled "Indian Ocean" about the 2004 tsunami disaster. The song featured Indian composer/producer A. R. Rahman, A-ha keyboard player Magne Furuholmen and Travis drummer Neil Primrose. Proceeds of the single went to help orphans in Banda Aceh, one of the areas worst affected by the tsunami, through Islam's Small Kindness charity. At first, the single was released only through several online music stores but later highlighted the compilation album Cat Stevens: Gold.
On 28 May 2005, Yusuf Islam delivered a keynote speech and performed at the Adopt-A-Minefield Gala in Düsseldorf. The Adopt-A-Minefield charity, under the patronage of Sir Paul McCartney, works internationally to raise awareness and funds to clear landmines and rehabilitate landmine survivors. Yusuf Islam attended as part of an honorary committee which also included Sir George Martin, Sir Richard Branson, Dr. Boutros Boutros-Ghali, Klaus Voormann, Christopher Lee and others.
In mid-2005, Yusuf Islam played guitar for the Dolly Parton album, Those Were the Days, on her version of his "Where Do the Children Play".  (Parton had also covered "Peace Train" a few years earlier.)
In May 2006, in anticipation of his forthcoming new pop album, the BBC1 programme "Imagine" aired a 49-minute documentary with Alan Yentob called Yusuf: The Artist formerly Known as Cat Stevens. This documentary film features rare audio and video clips from the late 1960s and 1970s,  as well as an extensive interview with Yusuf Islam, his brother, several record executives, Bob Geldof, Dolly Parton, and others outlining his career as Cat Stevens, his conversion and emergence as Yusuf Islam, and his return to music in 2006. There are clips of him singing in the studio when he was recording An Other Cup as well as a few 2006 excerpts of him on guitar singing a few verses of Cat Stevens songs including "The Wind" and "On the Road to Find Out".
Yusuf has credited his 21 year old son Muhammad Islam, also a musician and artist, for his return to secular music, when the son brought a guitar back into the house, which Yusuf began playing. Muhammad's professional name is believed to be "Yoriyos" and his debut album was released in February 2007. Yoriyos also created the art on Yusuf's album An Other Cup.
Starting in 2006, the Cat Stevens song "Tea for The Tillerman" was used as the theme tune for the Ricky Gervais BBC-HBO sitcom Extras. A Christmas-season television commercial for gift-giving by the diamond industry aired in 2006 with Cat Power's cover of "How Can I Tell You".
In December 2006, Yusuf was one of the artists that performed at the Nobel Peace Prize Concert in Oslo, Norway, in honour of the prize winners, Muhammad Yunus and Grameen Bank. He performed the songs "Midday (Avoid City After Dark)," "Peace Train," and "Heaven/Where True Love Goes." Yusuf also gave a concert in New York City that month as a "Jazz at Lincoln Center" event, recorded and broadcast by KCRW-FM radio, along with an interview by Nic Harcourt. Accompanying Yusuf on guitar was Alun Davies, who played guitar on many of his Cat Stevens records.
In April 2007, BBC1 broadcast a concert given at the Porchester Hall by Yusuf as part of BBC Sessions, his first live performance in London in 28 years (the previous being the UNICEF Year of the Child concert in 1979.) He played many new songs along with some of his classics, "Father & Son", "The Wind", "Where Do the Children Play?", "Don't Be Shy", "Wild World", and "Peace Train".
In July 2007, Yusuf performed at a concert in Bochum, Germany, in benefit of Archbishop Desmond Tutu's Peace Centre in South Africa and the Milagro Foundation of Deborah and Carlos Santana. The audience included Nobel Laureates Mikhail Gorbachev, Desmond Tutu and other prominent global figures. He later appeared as the finale act in the German leg of Live Earth in Hamburg performing some classic Cat Stevens songs and more recent compositions reflecting his concern for peace and child welfare. His set included Stevie Wonder's "Saturn", "Peace Train", "Where Do the Children Play?", "Ruins", and "Wild World".
Yusuf performed at the Peace One Day concert at the Royal Albert Hall on 21st September 2007.
In March 2006, Yusuf Islam finished recording his first all-new pop album since 1978. The album, An Other Cup, was released internationally in November 2006 on his own label, Ya Records (distributed by Polydor Records in the UK  and internationally by Atlantic Records) - the 40th anniversary of his first album, Matthew and Son.  A single was simultaneously released from the album, called "Heaven/Where True Love Goes". The album was produced with Rick Nowels, who has worked with Dido and Rod Stewart.  The performer is noted as "Yusuf", with a cover label identifying him as "the artist formerly known as Cat Stevens".  The art on the album is credited to Yoriyos. Yusuf Islam wrote all of the songs except "Don't Let Me Be Misunderstood", and recorded it in the United States and the United Kingdom.
Yusuf actively promoted this album, appearing on radio and television and in print interviews.  He was interviewed by the BBC in November 2006, "It's me, so it's going to sound like that of course . . . This is the real thing. . . . When my son brought the guitar back into the house, you know, that was the turning point. It opened a flood of, of new ideas and music which I think a lot of people would connect with."
Asked in a November 2006 Billboard magazine interview about why the artist is credited as "Yusuf" rather than "Yusuf Islam", he said, "Because 'Islam' doesn't have to be sloganized. The second name is like the official tag, but you call a friend by their first name. It's more intimate, and to me that's the message of this record."
As for why the sleeve says "the artist formerly known as Cat Stevens",  he responded, "That's the tag with which most people are familiar; for recognition purposes I'm not averse to that. For a lot of people, it reminds them of something they want to hold on to. That name is part of my history and a lot of the things I dreamt about as Cat Stevens have come true as Yusuf Islam."
On CBS Sunday Morning in December 2006, Yusuf Islam said, "You know, the cup is there to be filled . . . with whatever you want to fill it with.  For those people looking for Cat Stevens, they'll probably find him in this record. If you want to find Yusuf, go a bit deeper, you'll find him."
Stevens was nominated to be inducted into the Rock and Roll Hall of Fame in 2005, but not voted in.
On 10 November 2004, Yusuf Islam was presented with a Man for Peace award by the private foundation of former USSR president Mikhail Gorbachev, for his 'dedication to promote peace, the reconciliation of people and to condemn terrorism'; the ceremony was held in Rome, Italy and attended by five Nobel Peace Prize laureates. A year later, on 4 November 2005, he was awarded an honorary doctorate by the University of Gloucestershire for services to education and humanitarian relief. In October 2003 he received the World Social Award for "humanitarian relief work helping children and victims of war".
On 20 October 2005, Yusuf Islam was named ASCAP's Songwriter of the Year and received Song of the Year honours for "The First Cut Is the Deepest", at a special presentation in London. At the ceremony, The American Society of Composers, Authors and Publishers (ASCAP) honoured the top British writer and publisher members of the UK's Performing Rights Society.
On 11 October 2006, Yusuf Islam was named Songwriter of the Year for the second year running and received another award for the same song "The First Cut Is the Deepest".
On 4 January 2007, Yusuf Islam was awarded the Mediterranean Prize for Peace in Naples, Italy.  He received the award "as a result of the work he has done to increase peace in the world".
On 25 March 2007, he received the German ECHO "special award for life achievements as musician and ambassador between cultures" in Berlin
On 24 May 2007, Yusuf Islam was awarded the Ivor Novello award for Outstanding Song Collection, in a ceremony held in London.
On 10 July 2007, Yusuf Islam was awarded an honorary doctorate (LLD) by the University of Exeter, in recognition of "his humanitarian work and improving understanding between Islamic and western cultures". The ceremony was attended by esteemed personalities including Professor Ekmeleddin Ihsanoglu and guitarist Brian May.
