(53) باب رَضَاعِ الْكَبِيرِ .
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 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.'"
