IN: Umar was born in Mecca to the Banu Adi clan, which was responsible for arbitration among the tribes. His father was Khattab ibn Nufayl and his mother was Hantama bint Hisham, from the tribe of Banu Makhzum. In his youth he used to tend to his father's camels in the plains near Mecca. His merchant father was famed for his intelligence among his tribe.

While under his leadership, the empire expanded and he also began to build a political structure that would hold together the vast empire. He undertook many administrative reforms and closely oversaw public policy. He established an advanced administration for the newly conquered lands, including several new ministries and bureaucracies, and ordered a census of all the Muslim territories. During his rule, the garrison cities (amsar) of Basra and Kufa were founded or expanded. In 638, he extended and renovated the Masjid al-Haram (Grand Mosque) in Mecca and Al-Masjid al-Nabawi (Mosque of the Prophet) in Medina. Umar also ordered the expulsion to Syria and Iraq of the Christian and Jewish communities of Najran and Khaybar. He also permitted Jewish families to resettle in Jerusalem, which had previously been barred from all Jews. He issued orders that these Christians and Jews should be treated well and allotted them the equivalent amount of land in their new settlements. Umar also forbade non-Muslims to reside in the Hejaz for longer than three days. He was first to establish the army as a state department. Umar was founder of Fiqh, Islamic jurisprudence. He is regarded by Sunni Muslims to be one of the greatest Faqih. Umar as a jurist started the process of codifying Islamic Law. In 641, he established Bayt al-mal, a financial institution and started annual allowance for the Muslims. As a leader, 'Umar was known for his simple, austere lifestyle. Rather than adopt the pomp and display affected by the rulers of the time, he continued to live much as he had when Muslims were poor and persecuted. In 638, his fourth year as caliph and the seventeenth year 17 since the Hijra, he decreed that the Islamic calendar should be counted from the year of the Hijra of Muhammad from Mecca to Medina.

was there another reform?

OUT: he extended and renovated the Masjid al-Haram (Grand Mosque) in Mecca and Al-Masjid al-Nabawi (Mosque of the Prophet) in Medina.

IN: Alvin and the Chipmunks, originally David Seville and the Chipmunks or simply The Chipmunks, is an American animated music group created by Ross Bagdasarian Sr. for a novelty record in 1958. The group consists of three singing animated anthropomorphic chipmunks: Alvin, the mischievous troublemaker, who quickly became the star of the group; Simon, the tall, bespectacled intellectual; and Theodore, the chubby, impressionable one. The trio is managed by their human adoptive father, David (Dave) Seville. In reality, "David Seville" was Bagdasarian's stage name, and the Chipmunks themselves are named after the executives of their original record label.

In addition to having an IQ just north of Einstein, Simon possesses a dry sense of humor as well as keen wit. He is kind, gentle, logical, and at times poetic. He often takes charge when Alvin goes too far with his harebrained schemes. Although Simon tends to disagree with Alvin and even argue with him, he truly loves his brother and sticks by him despite everything. He wears glasses and blue attire, and has blue eyes. Simon plays the bass, bass clarinet, saxophone, bagpipes, tuba, and drums, among others. In vocal harmonies, he consistently sings the lower parts due to having a deeper voice than his brothers. He is shown playing the keyboard in the original open for the 1980s series. He was also shown playing guitar in a 1980s Hardee's commercial. Simon is often implied to have a crush on Jeanette, as she is like him in many details; wearing glasses and blue and purple attire and having a high IQ, possibly rivalling his own. However, he seems braver in standing up to siblings than her because Jeanette doesn't often stand up for herself when Brittany pushes her around, but like Simon to Alvin, Jeanette shares a sisterly bond with Brittany. In one animated episode, a chemistry experiment gone wrong resulted in Simon becoming a handsome, Casanova-like romancer. He called himself "Mr. Heartthrob" (an obvious parody of Mr. Hyde), and enchanted every girl he met before being returned to normal. Like his brothers, he was originally voiced by Ross Bagdasarian Sr. In the animated series and film, he was voiced by Ross Bagdasarian Jr. Matthew Gray Gubler voiced Simon in the live-action/animated film series.
