God has put rules and regulations for marriage dissolution (talaq) to safeguard wives and husbands rights when the relationship between them becomes very restrained and there is no way to save their marriage.
Definition and status
Divorce, or talaq in Arabic, means the dissolution of the marital bond.
Allah has put in place a complete system of rulings and practices, requiring both man and wife to heed them and to maintain an amicable relationship so that their marriage lasts for life. However, one or both of them may not heed these, which may lead to a strained relationship. If this is aggravated, reconciliation may become hard to achieve. Hence, it is necessary to put in place rules and regulations for the termination of the marriage in a way that safeguards the rights of both man and wife.
