وَعَنْهَا قَالَتْ: { جَاءَتْ سَهْلَةُ بِنْتُ سُهَيْلٍ. فَقَالَتْ: يَا رَسُولَ اَللَّهِ! إِنَّ سَالِمًا مَوْلَى أَبِي حُذَيْفَةَ مَعَنَا فِي بَيْتِنَا, وَقَدْ بَلَغَ مَا يَبْلُغُ اَلرِّجَالُ. قَالَ:
"أَرْضِعِيهِ. تَحْرُمِي عَلَيْهِ"
Narrated ['Aishah (RA)]:
Sahlah (RA) daughter of Suhail (RA) came and said, "O Allah's Messenger, Salim the manumitted slave of Abu Hudhaifah lives with us in our house; and he has attained what men attain (i.e. puberty)." He said, "Suckle him so you would become unlawful to him (in marriage)." [Reported by Muslim].
