Sahih Muslim Book 008, Hadith Number 3429.

Chapter: Suckling of a young (boy).

Umm Salama, the wife of Allah's Apostle (May peace be upon him), used to say that all wives of Allah's Apostle (May peace be upon him) disclaimed the idea that one with this type of fosterage (having been suckled after the proper period) should come to them and said to 'Aisha: By Allah, we do not find this but a sort of concession given by Allah's Messenger (May peace be upon him) only for Salim, and no one was going to be allowed to enter (our houses) with this type of fosterage and we do not subscribe to this view.
