Saʿd ibn Abī Waqqās known as Saʿd ibn Malik, was one of the companions of the Islamic prophet. Saʿd was the seventh person to embrace Islam, which he did at the age of seventeen, he is known for his commandership in the Battle of al-Qadisiyyah and in the conquest of Persia in 636, his governorship over Persia, his diplomatic sojourns to China in 651. Saʿd was born in Mecca in 595, his father was Abu Waqqas Malik ibn Uhayb ibn Abd Manaf ibn Zuhrah from the Banu Zuhrah clan of the Quraysh tribe. Uhayb ibn Abd Manaf was the paternal uncle of mother of Muhammad. Saʿd's mother was Hamnah bint Sufyan ibn Umayya ibn Abd Shams ibn Abd Manaf, he was seventeen years old. He had many children, among whom his sons Umar and Aamir and his daughter A'isha are the most well-known, he was one of the first to accept Islam. Saʿd relates: This was referenced in the Quranic verse 31:14–15. In 614, the Muslims were on their way to the hills of Mecca to offer prayer with Muhammad, when a group of polytheists observed them.

They began to fight them. Sa`ad beat a polytheist and shed his blood becoming the first Muslim to shed blood in the name of Islam, he fought at the battle of Badr with his young brother ʿUmayr. Being only in his early teens, Umayr was denied access to battle, but after struggling and crying, he was given permission by Muhammed to fight in battle. Saʿd returned to Medina alone. At the battle of Uhud, Saʿd was chosen as an archer together with Saʿīb and others. Saʿd was among those who fought in defense of Muhammad after some Muslims had deserted their positions. Muhammad honoured him by declaring him one of the best archers of that time. During the battle, Muhammad gathered some arrows for him, he fell ill during the Farewell Pilgrimage, he had only a daughter during this period. Sa'ad said: O Messenger of Allah. I have wealth and I only have one daughter to inherit from me. Shall I give two thirds of my wealth as Sadaqah?" "No," replied the Prophet. "Then, a half?." asked Sa'ad and the Prophet again said'no.'

"Then, a third?' asked Sa'ad. "Yes," said the Prophet. "The third is much. Indeed to leave your heirs well-off is better than that you should leave them dependent on and to beg from people. If you spend anything seeking to gain thereby the pleasure of Allah, you will be rewarded for it if it is a morsel which you place in your wife's mouth. Sa` ad Ibn Abi Waqqas, was the one who built the city of Kufa in Iraq during the reign Umar ibn al-Khattab. Saʿd fought under ʿUmar's command against the Sassanid army at the Battle of al-Qādisiyyah and Battle of Nahāvand, he was appointed governor of Kufa and Nejd during the caliphate of ʿUmar. Some narrations state that although ʿUmar deposed him from his post as governor, he recommended that the caliph who succeeded him reinstall Saʿd, since Umar had not deposed Saʿd due to any treachery, he was one of six people nominated by Umar ibn al-Khattab for the third caliphate. ʿUthman carried out appointed Saʿd as governor of Kufa. Saʿd has been traditionally credited by Chinese Muslims with introducing Islam to China in 650, during the reign of Emperor Gaozong of Tang.

He outlived all ten blessed companions, died a wealthy man at the age of eighty, around the year 674. Saʿd is among the ten promised paradise. Sunni Muslims regard him as one of the ten. One Sunni source states: To urge him on, Muhammad said: "Shoot, Saʿd...may my mother and father be your ransom.". This was reported by Ali ibn Abi Talib, who said that he had not heard Muhammad promise such a ransom to anyone, except to Saʿd ibn Malik. Bukhari, Volume 5, Book 59, Number 389.
