Maliks Muwatta Book 29, Hadith Number 21.

Section : Dhihar of Free Men.

Yahya related to me from Malik that he had heard that a man asked al-Qasim ibn Muhammad and Sulayman ibn Yasar about a man who pronounced dhihar from his wife before he had married her. They said, “If he marries her, he must not touch her until he has done the kaffara for pronouncing dhihar.”
