Salaams brother just a snip-it of Umar's early life:
Umar (ra) was born in Mecca around 580 AD to the Banu Adi clan, which was responsible for arbitrations among the tribes of Makkah. His father was Khattab ibn Nufayl and his mother was Hantama bint Hisham, from the tribe of Banu Makhzum. In his youth, Umar (ra) used to tend to his father’s camels in the plains near Mecca. His father was famed for his intelligence among his tribe. He was a middle class merchant and is believed to be a ruthless man who often treated Umar (ra) harshly. As obvious from Umar's (ra) own statement regarding his father, Umar (ra) said, "My father Al-Khattab was a ruthless man. He used to make me work hard; if I didn't work he used to beat me and he used to work me to exhaustion."
