What is the ruling on a wife not receiving her dowry as stipulated in the contract, and is this considered a deficiency that affects her relationship with her husband?

The dowry (mahr) is obligatory for the woman. If it is not agreed upon at the time of the contract, the marriage is still valid, and she is entitled to a dowry equivalent to that of women of her status (mahr al-mithl). If a specific dowry is agreed upon, it must be adhered to. The wife has the right to demand her prompt dowry (mahr mu'ajjal) and may refuse to surrender herself until she receives it. As for the deferred dowry (mahr mu'ajjal), it cannot be demanded except at its appointed time. The issue of the dowry should be resolved calmly, and its causes ascertained, while preserving marital affection and harmony.
