It is narrated from Sayyidah Aishah (may Allah be pleased with her) that one night I was late in coming to the Messenger of Allah (peace and blessings be upon him) after the Isha prayer. When I came, he (peace and blessings be upon him) asked me: "Where were you?" I said: I was listening in the mosque to the recitation of a man from among your Companions; I have not heard a melodious voice and recitation like his from anyone else among your Companions. So he (peace and blessings be upon him) stood up, and I went along with him, until he listened to his recitation. Then he turned to me and said: "This is Salim, the freed slave of Abu Hudhayfah. Praise be to Allah, who has brought forth in my Ummah a person of such excellence as him." This hadith is sahih (authentic) on the condition of the two Shaykhs, but they did not record it with these words. However, they both agreed on recording the narration of Ubaydullah from Nafi' from Sayyiduna Ibn Umar (may Allah be pleased with them both) that when the Muhajirun came from Makkah to Madinah, Salim, the freed slave of Abu Hudhayfah, used to lead them in prayer, because he had the most knowledge of the Qur'an among them.

It is narrated from Sayyidah Aishah (may Allah be pleased with her) that the wife of Sayyiduna Abu Hudhayfah (may Allah be pleased with him) mentioned to the Messenger of Allah (peace and blessings be upon him) that Salim, the freed slave of Abu Hudhayfah, came in to her freely (in his status as an adopted son) (while he had reached adulthood). So the Messenger of Allah (peace and blessings be upon him) said to her: "Breastfeed him." So she breastfed him after Salim had taken part in the Battle of Badr (so that the prohibition of fosterage would be established), and thereafter he used to come in to her without hesitation. This hadith is sahih (authentic) on the condition of Imam Muslim, but the two Shaykhs did not record it.
