All perfect praise be to Allaah, The Lord of the Worlds. I testify that there is none worthy of worship except Allaah, and that Muhammad, sallallaahu ‘alayhi wa sallam, is His slave and messenger.
reported that the Prophet, sallallaahu ‘alayhi wa sallam, said: “It is sufficient sin for a man that he neglects those he is responsible to maintain.” [Ahmad and Abu Daawood]
Please refer to Fataawa 86618, 88304 and 85012.
We advise you to supplicate Allaah to guide him to that which is best for him and bless him with guidance and repentance. The wife is also advised to seek the mediation of respected people whose advice is most likely to be accepted by him. For further information, please refer to Fataawa 120659 and 136875.
If he turns back to Allaah in repentance, this is good and praise be to Allaah for that. However, if he does not repent from such misdeeds, his wife is entitled to demand divorce. In fact, seeking divorce would be better in this case as there is no good in remaining married to such a man. Please refer to Fatwa 131953 on the legitimate reasons for seeking divorce.
In case of divorce, the custody of the children is granted to the mother as long as she is not married. The mother’s right to custody is lost when she remarries, and it transfers to the one who has most right to that after her, which is the mother’s mother. For more details, kindly refer to Fatwa 84618.
It should be highlighted that the father is obliged to provide for his children even if they are in the custody of the mother.
However, if she chooses to adhere to patience and remain married to that man, she may do so. For more benefit, please refer to Fatwa 85044.
We would like to point out that the Muslim should make a deliberate decision when choosing the spouse-to-be. Istikhaarah (guidance-seeking prayer) and consultation are required. Indeed, he who resorts to Istikhaarah and consultation will succeed, Allaah willing.
Allaah Knows best.
