Musannaf Ibn Abi Shaybah

Hasan (may Allah have mercy on him) says that if a man accuses his wife of adultery and then retracts his statement, it is not permissible for the woman to remain with that man. She should take the matter to the judge, and then either the prescribed punishment will be carried out on the man or there will be li'an (mutual cursing).

Ibrahim (may Allah have mercy on him) said that if a group retracts their statement, then both should remain together, and a person should seek forgiveness from Allah and resolve not to do so again.

Hazrat Sha'bi (may Allah have mercy on him) says that if a man accuses his wife of adultery, then if he wishes, he may retract his statement, and the punishment of qazf will be carried out upon him, and that woman will remain his wife.

Hazrat Sha'bi (may Allah have mercy on him) says regarding the man who accuses his wife of adultery but does not present the matter before the judge's court, that if he retracts his statement, the marriage will remain intact.
