Is it obligatory for a man who apostatizes while married to renew the marriage contract if he repents from the apostasy?

Question:
May Allah reward you, Honorable Shaykh. This questioner says: If a man apostatizes while he is married, is it obligatory for him to renew the contract if he returns to Islam, his Islam is good, and he repents from the apostasy?

Answer:
If he apostatizes while married, his wife remains in the waiting period. If he repents, he is separated from his wife, and his wife remains in the waiting period. If he repents during the waiting period, she returns to him; his wife returns to him. However, if he persists in the apostasy, his wife is divorced from him. Or, if his wife exits the waiting period—his wife exits the waiting period—and he has not repented, she is divorced from him by the expiration of the waiting period. If he then repents to Allah and wants to marry her with a new contract, there is no harm; he repents to Allah and marries her with a new contract, and there is no harm. But if he repents during the waiting period, she returns to him. If he does not repent until after the waiting period has ended, he may marry her with a new contract. Yes.
