I was late returning one night during the time of the Messenger of Allah ﷺ, after the evening prayer. When I came back, he asked, "Where were you?"I replied, "I was listening to the recitation of one of your companions. I have never heard anyone recite or have a voice like his."She said, He got up and I went with him until he listened to the man. Then he turned to me and said, "This is Salim, the freed slave of Abu Huzaifa. Praise be to Allah, who has placed someone like this among my community."
أبطأت على عهد رسول الله ﷺ ليلة بعد العشاء، ثم جئت فقال: أين كنت؟ قلت: كنت أستمع قراءة رجل من أصحابك لم أسمع مثل قراءته وصوته من أحد. قالت: فقام وقمت معه حتى استمع له، ثم التفت إلي فقال: هذا سالم، مولى أبي حذيفة، الحمد لله الذي جعل في أمتي مثل هذا.
Ibn Majah (1338) and Ahmad (25320) narrated it, and Hakim graded it sahih (3/226), all of them through various chains, from Hanzala bin Abu Sufyan, that he heard Abdul-Rahman bin Sabit Jumahi narrate from Ayesha, the wife of the Prophet ﷺ, who said... and then he related it. Its chain of transmission is sahih. Busiri also graded it sahih in Misbah Zujaja.Among the reports about Salim, the freed slave of Abu Huzaifa, is that he was the one among the people who had memorized the most of the Quran.
