[Machine] She had with her and that she heard the voice of a man seeking permission in the house of Hafsah, so Aisha said, "O Messenger of Allah, there is a man seeking permission in your house." The Messenger of Allah ﷺ said, "Do I see him as a foster brother of Hafsah from breastfeeding?" So I said, "O Messenger of Allah, if he is a foster brother of hers from breastfeeding, can he enter upon me while she is alive?" The Messenger of Allah ﷺ said, "Yes, breastfeeding prohibits what childbirth prohibits." This is the wording of the Hadith reported by Ash-Shafi'i.
ﷺ كَانَ عِنْدَهَا وَأَنَّهَا سَمِعَتْ صَوْتَ رَجُلٍ يَسْتَأْذِنُ فِي بَيْتِ حَفْصَةَ فَقَالَتْ عَائِشَةُ ؓ فَقُلْتُ يَا رَسُولَ اللهِ هَذَا رَجُلٌ يَسْتَأْذِنُ فِي بَيْتِكَ فَقَالَ رَسُولُ اللهِ ﷺ أُرَاهُ فُلَانًا لِعَمِّ حَفْصَةَ مِنَ الرَّضَاعَةِ فَقُلْتُ يَا رَسُولَ اللهِ لَوْ كَانَ فُلَانًا حَيًّا لِعَمِّهَا مِنَ الرَّضَاعَةِ يَدْخُلُ عَلَيَّ؟ فَقَالَ رَسُولُ اللهِ ﷺ نَعَمْ إِنَّ الرَّضَاعَةَ تُحَرِّمُ مَا تُحَرِّمُ الْوِلَادَةُ لَفْظُ حَدِيثِ الشَّافِعِيِّ
