It was narrated that 'Urwah said:

"The rest of the wives of the Prophet refused for anyone to enter upon them on the basis of that type of breastfeeding, meaning breastfeeding of an adult. They said to 'Aishah: 'By Allah, we think that what the Messenger of Allah told Sahlah bint Suhail to do was a concession which was granted by the Messenger of Allah only with regard to breastfeeding Salim. By Allah, no one will enter upon us, nor see us on the basis of this type of breastfeeding.'"

أَخْبَرَنَا يُونُسُ بْنُ عَبْدِ الأَعْلَى، قَالَ أَنْبَأَنَا ابْنُ وَهْبٍ، قَالَ أَخْبَرَنِي يُونُسُ، وَمَالِكٌ، عَنِ ابْنِ شِهَابٍ، عَنْ عُرْوَةَ، قَالَ أَبَى سَائِرُ أَزْوَاجِ النَّبِيِّ ﷺ أَنْ يَدْخُلَ عَلَيْهِنَّ بِتِلْكَ الرَّضْعَةِ أَحَدٌ مِنَ النَّاسِ - يُرِيدُ رَضَاعَةَ الْكَبِيرِ - وَقُلْنَ لِعَائِشَةَ وَاللَّهِ مَا نُرَى الَّذِي أَمَرَ رَسُولُ اللَّهِ ﷺ سَهْلَةَ بِنْتَ سُهَيْلٍ إِلاَّ رُخْصَةً فِي رَضَاعَةِ سَالِمٍ وَحْدَهُ مِنْ رَسُولِ اللَّهِ ﷺ وَاللَّهِ لاَ يَدْخُلُ عَلَيْنَا أَحَدٌ بِهَذِهِ الرَّضْعَةِ وَلاَ يَرَانَا .
