Muwatta Malik (Yahya) 1155 — Zihar (declaring wife as unlawful)

It reached Imam Malik, may Allah have mercy on him, that a man asked Qasim bin Muhammad and Sulaiman bin Yasar: What if a person pronounces zihar to a woman before marriage? Both of them said: If that person marries that woman, he should not have intercourse with her until he has offered the expiation for zihar.
