[Machine] Aisha, the wife of the Prophet ﷺ , informed him that the Messenger of Allah ﷺ was with her and that she heard the sound of a man seeking permission to enter Hafsa's house. Aisha said to him, "O Messenger of Allah, a man seeking permission to enter your house." The Messenger of Allah ﷺ said, "I think it is so-and-so, who is brother in nursing to Hafsa." Aisha said, "O Messenger of Allah, if he were alive, would he have entered upon me?" The Messenger of Allah ﷺ said, "Yes, for breastfeeding prohibits what birth prohibits."
أَنَّ عَائِشَةَ زَوْجَ النَّبِيِّ ﷺ أَخْبَرَتْهَا أَنَّ رَسُولَ اللهِ ﷺ كَانَ عِنْدَهَا وَأَنَّهَا سَمِعَتْ صَوْتَ رَجُلٍ يَسْتَأْذِنُ فِي بَيْتِ حَفْصَةَ قَالَتْ عَائِشَةُ فَقُلْتُ يَا رَسُولَ اللهِ رَجُلٌ يَسْتَأْذِنُ فِي بَيْتِكَ قَالَتْ فَقَالَ رَسُولُ اللهِ ﷺ أَرَاهُ فُلَانًا لِعَمِّ حَفْصَةَ مِنَ الرَّضَاعَةِ فَقَالَتْ عَائِشَةُ يَا رَسُولَ اللهِ لَوْ كَانَ فُلَانٌ حَيًّا لِعَمِّهَا مِنَ الرَّضَاعَةِ دَخَلَ عَلَيَّ؟ فَقَالَ رَسُولُ اللهِ ﷺ نَعَمْ إِنَّ الرَّضَاعَةَ تُحَرِّمُ مَا تُحَرِّمُ الْوِلَادَةُ
