Preferring daughters over sons due to their obedience

A: It is obligatory for the Muslim to be just as regards giving gifts to his male and female children. It is authentically reported that the Prophet (peace be upon him) said in the Hadith on the authority of Al-Nu`man ibn Bashir (may Allah be pleased with them both): Be afraid of Allah, and be just to your children. Willing a part of the estate to be given to the inheritor is invalid in the Shari`ah of Allah (Exalted be He), even if you will register them in the inheritor's names and get a nominal and not actual price in return. If you register the estate you give to them through an actual sale contract, there is no harm in that. (Part No. 16; Page No. 200) You have to know that giving a part of your estate to your daughters and not doing the same with your sons will not stop your sons from making intrigues against them. It is more likely to arouse their wrath, grudge, envy and harm against their sisters. So you should fear Allah and treat your sons and daughters justly. You should give your children their shares according to the rules of inheritance and hand them their documents so that they would use them freely as long as they are grown-ups and leave your estate to be distributed after your death. May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
