"The rest of the wives of the Prophet refused for anyone to enter upon them on the basis of that type of breast-feeding, meaning breast-feeding 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 breast-feeding Salim. By Allah, no one will enter upon us, nor see us on the basis of this type of breast-feeding.'" (Using translation from Nasāʾī 3324)  

أَبَى سَائِرُ أَزْوَاجِ النَّبِيِّ ﷺ أَنْ يَدْخُلَ عَلَيْهِنَّ أَحَدٌ مِنَ النَّاسِ بِتِلْكَ الرَّضَاعَةِ يُرِيدُ رَضَاعَةِ الْكَبِيرِ وَقُلْنَ لِعَائِشَةَ وَاللهِ مَا نَرَى الَّذِي أَمَرَ رَسُولُ اللهِ ﷺ سَهْلَةَ بِنْتَ سُهَيْلٍ إِلَّا رُخْصَةً فِي رَضَاعَةِ سَالِمٍ وَحْدَهُ مِنْ رَسُولِ اللهِ ﷺ وَاللهِ لَا يَدْخُلُ عَلَيْنَا أَحَدٌ بِهَذِهِ الرَّضْعَةِ وَلَا يَرَانَا خَالَفَهُمَا عُقَيْلٌ
