Messenger of Allah, Salim (the freed slave of Abu Hudhaifa) is living with us in our house, and he has attained (puberty) as men attain it and has acquired knowledge (of the sex problems) as men acquire, whereupon he said: Suckle him so that he may become unlawful (in regard to marriage) for you He (Ibn Abu Mulaika) said: I refrained from (narrating this hadith) for a year or so on account of fear. I then met al-Qasim and said to him: You narrated to me a hadith which I did not narrate (to anyone) afterwards. He said: What is that? I informed him, whereupon he said: Narrate it on my authority that 'A'isha (Allah be pleased with her) had narrated that to me. (Using translation from Muslim 1453c)
أَنَّ سَهْلَةَ بِنْتَ سُهَيْلِ بْنِ عَمْرٍو جَاءَتْ رَسُولَ اللهِ ﷺ فَقَالَتْ يَا رَسُولَ اللهِ إِنَّ سَالِمًا مَوْلَى أَبِي حُذَيْفَةَ مَعَنَا فِي بَيْتِنَا وَقَدْ بَلَغَ مَا يَبْلُغُ الرِّجَالُ وَقَدْ عَلِمَ مَا يَعْلَمُ الرِّجَالُ فَقَالَ النَّبِيُّ ﷺ «أَرْضِعِيهِ تَحْرُمِي عَلَيْهِ»
