Salim Mawla Abu-Hudhayfah (سالم مولى أبي حذيفة) was one of the sahaba of Muhammad. He was named so since he was the freed slave of Abu Hudaifah ibn Utbah, see Mawla.
He participated in the battle against Musaylimah as a standard bearer of the Muhajireen and displayed unexpected valour. His people feared that he would show weakness or be too terrified to fight. To them he said, "If you manage to overtake me, what a miserable bearer of the Qur'an I shall be." He then valiantly plunged into the enemy ranks and eventually died in battle.
Muhammad is quoted by Sunnis as saying:
Taha Husain, a 20th century Sunni Islamic scholar
| “ | When Umar was dying, he was questioned about his successor, and he said: ‘If Abu Obaida bin al-Jarrah were alive, I would have made him the khalifa. If Khalid bin al-Walid were alive, I would have appointed him the amir of the Muslims. And if Salim, the client of Abu Hudhaifa, were living today, then I would have designated him as your ruler.' This Salim was a slave who came from Istakhar in Persia. He was emancipated, and became a ‘mawali' (client) of Abu Hudhaifa. He was well-known for his piety. Many Muslims deferred to him in matters of Faith even in the times of Muhammad. Sometimes he led the Muslims in prayer also. He was killed in the Ridda wars during the khilafat of Abu Bakr. He was a devout and God-fearing man.[1] | ” |
Ali Asgher Razwy, a 20th century Shi'a Twelver Islamic scholar states:
| “ | It was really unfortunate for the umma that Salim was dead or else Umar would have made him his successor, and he might have made an excellent khalifa.[2] | ” |
He had contributed in all major battles, such as Badar,Uhud,Ahzab etc.,so he is the Badarian companion of the Prophet Muhammad (Peace be up on him).
