One of the pious teachers of the Qur’an among the companions was Salim bin Ma’qil (RA).
Salim roots were from Istakhr, which is in the southern portion of modern day Iran. He was the first black companion of the Prophet (SAWS) mentioned in Tanwir Al-Ghabash written by Hanbali scholar ibn Al-Jawzi, a book that chronicles Arab relations between Africans and early Muslims who were black.
Salim embraced Islam in Makkah and was freed from slavery, becoming a client of Abu Hudhayfah. He was one who migrated to Al-Madinah for the sake of Allah (SWT). Abdullah bin ‘Umar said that he was the most knowledgeable in the Qur’an of those who first migrated to Al-Madinah. Later on in Al-Madinah, the Prophet (SAWS) told the people that they should learn the Qur’an from four companions, those being Abdullah bin Mas’ud, Salim Mawla Abi Hudhayfah, Ubay bin Ka’ab and Mu’adh bin Jabal.
Salim accompanied Khalid bin Al-Walid, who was the general sent by the Prophet (SAWS), to get allegiance from the Tribe of Jadhimah through Islam or have them pay taxes. Even though the men of Jadhimah declared Islam upon their visitation, Khalid began to kill them anyway. Salim reprimanded Khalid and listed off to him the crimes that he committed according to the sacred law. When word got back to the Prophet (SAWS) regarding Khalid’s unlawful killings, the Prophet (SAWS) proclaimed loudly, “Oh Allah! Surely I am free of what Khalid has done!” The Prophet (SAWS) said of Salim that “Allah loves the truth from his heart.”
In Ghazwah Al-Yamamah, Salim urged the Muslims on by chanting, “Oh People of the Qur’an! Beautify the Qur’an with your deeds!” When the standard bearer Zayd bin al-Khattab was martyred, Salim lifted the standard. When his right hand was severed in the battle, he then continued by lifting it with his left hand. In this battle, Salim achieved martyrdom next to Abu Hudhayfah, his client.
