5088. Narrated ‘Āishah رضي الله عنها: Abū Ḥudhaifa bin ‘Utba bin Rabī‘a bin ‘Abd-Shams who had witnessed the battle of Badr along with the Prophet ﷺ, adopted Sālim as his son, to whom he married his niece, Hind bin Al-Walid bin ‘Utba bin Rabī‘a; and Sālim was the freed slave of an Anṣārī woman, just as the Prophet ﷺ, had adopted Zaid as his son. It was the custom in the pre-Islāmic period that if somebody adopted a boy, the people would call him the son of the adoptive father and he would be the latter's heir. But when Allāh revealed the Divine Verses: "Call them (adopted sons) by (the names of) their fathers (up to) and Mawālikum (your freed slaves)." (V.33:5), the adopted persons were called by their father's names. The one whose father was not known, would be regarded as a Maulā and your brother in religion. Later on Sahla bint Suhail bin 'Amr Al-Qurashī Al-'Āmirī - and she was the wife of Hudhaifa bin 'Utba - came to the Prophet ﷺ and said, "O Allāh's Messenger! We used to consider Sālim as our (adopted) son, and now Allāh has revealed what you know (regarding adopted sons)." The subnarrator then mentioned the rest of the narration. (See H. 4000)
