Sa`ad ibn Abi Waqqas
He was from the Banu Zuhrah clan of the Quraysh tribe ,and was a maternal uncle of Muhammad. He had a son named `Umar ibn Sa`d and he was an early convert to Islam and one of the important .
He was one of the first to accept Islam
Sa'ad relates:
“ When my mother heard the news of my Islam, she flew into a rage. She came up to me and said: "O Sa'ad! What is this religion that you have embraced which has taken you away from the religion of your mother and father...? By God, either you forsake your new religion or I would not eat or drink until I die. Your heart would be broken with grief for me and remorse would consume you on account of the deed, you have done and people would censure you forever more.' 'Don't do (such a thing), my mother,' I said, 'for I would not give up my religion for anything.' However, she went on with her threat... For days she neither ate nor drank. She became emaciated and weak."
"Hour after hour, I went to her asking whether I should bring her some food or something to drink but she persistently refused, insisting that she would neither eat nor drink until she died or I abandoned my religion. I said to her, 'Yaa Ummaah! In spite of my strong love for you, my love for Allah and His Messenger is indeed stronger. By Allah, if you had a thousand souls and each one depart one after another, I would not abandon this religion for anything.' When she saw that I was determined she relented unwillingly and ate and drank.
In 614 the Muslims were on their way to the hills of Mecca to hold a clandestine meeting with Muhammad, when a group of polytheists observed their suspicious movements and began to abuse and fight them. Sa`ad beat a polytheist and shed his blood, reportedly the first instance of bloodshed in the history of Islam.
He fought at the battle of Badr with his young brother Umayr, who cried to accompany the Muslim army, as he was only in his early teens. Sa`d returned to al-Madīnah alone; Umayr was one of the fourteen Muslims who died in the battle.
Sa`d also fought under `Umar's command against the Sasanian army in the Battle of al-Qadisiyyah in Umar's bin al-kattab era
He lived until he was almost eighty years old. He died, a wealthy man, in the year 664.
