I’ve read a fatwa of Shaikh M.Al-Qaradawi that it is not prohibited for the husband to drink his wife’s milk. Jazak Allah Khair
Firstly, we need to realize that not every single aspect of Deen is proven directly from the Qur’aan and Hadith. Many aspects of Deen are proven through principles that are deduced from the Qur’aan and Hadith.
Based on the above, the Fuqahaa have ruled that it is Haraam for a man to drink the milk of his wife. However, one is allowed to fondle and touch the breasts of his wife if there is no fear of milk entering his mouth. (Fataawa Mahmoodiyah; Ahsanul Fataawa)
