وهب بن منبه
Major tribes, including Himyar, sent delegations to Medina during the "year of delegations" around 630–631 CE. Several Yemenis accepted Islam before the year 630, such as Ammar ibn Yasir, Al-Ala'a Al-Hadrami, Miqdad ibn Aswad, Abu Musa Ashaari, and Sharhabeel ibn Hasana. A man named 'Abhala ibn Ka'ab Al-Ansi expelled the remaining Persians and claimed he was a prophet of Rahman. He was assassinated by a Yemeni of Persian origin called Fayruz al-Daylami. Christians, who were mainly staying in Najran along with Jews, agreed to pay "jizyah" (), although some Jews converted to Islam, such as Wahb ibn Munabbih and Ka'ab al-Ahbar.
