If a woman stipulates conditions in the marriage contract, may she waive them?

Question : Peace be upon you. And upon you be peace. How are you, Shaykh Muhammad? I am well, praise be to Allah. I have some questions, Shaykh, may I ask them? There is no harm in that. If a woman stipulates a condition for her husband in the marriage contract, and then after the marriage she sees that she wants to waive this condition, does that have any effect on the contract?

Answer : Praise be to Allah, Lord of the worlds, and I send prayers and peace upon our Prophet Muhammad, the Seal of the Prophets and the Imam of the Pious, and upon his family and his Companions, and those who follow them in excellence until the Day of Judgment. As long as the right is hers, she may waive it. Good.
