Excerpt: Fatawa Aman Puri by Sheikh Ghulam Mustafa Zahir Aman Puri
Question:
Does breastfeeding after the period of suckling establish prohibition or not?
Answer:
The prohibition of breastfeeding is only established by drinking milk during the period of suckling, and that too by drinking to satisfaction at least five times.
❀Sayyida Aisha (may Allah be pleased with her) narrates that the Messenger of Allah (peace be upon him) said:
لا تحرم المصة ولا المصتان
"Drinking milk once or twice does not establish breastfeeding."
Reference: (Sahih Muslim: 1450)
Establishing prohibition does not occur by placing the breast in the mouth once or twice.
Reference: (Sahih Muslim: 1451)
