Stipulating that the wife abides by the Islamic rulings
Q: My brother wants to marry my daughter to his son. I agreed to his three stipulations:keeping up the congregational Salah (Prayer);letting the beard grow;and quitting smoking.I wanted to stipulate the same to his son and
write these stipulations in the marriage contract.
However, my brother, my father and my group became angry with me, and refused to write these stipulations in the contract, lest he may not apply them. However, I insisted on this. What is the ruling on this in Shari`ah (Islamic law)? Please advise, may Allah reward you and protect you. Should I insist on those stipulations or leave them to please my father, my brother and my group? What is Your Eminence's opinion? May Allah's Peace, Mercy, and Blessings be upon you.
You are right in making these stipulations in your daughter's marriage contract, and her husband should fulfill them. This is according to the saying of the Prophet (peace be upon him),
The stipulations most entitled to be abided by are those with which you are given the right to enjoy the (women’s) private parts (i.e. the stipulations of the marriage contract).
May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
