Impermissibility of preferring the sons over the daughters when giving grants
If the money that bought the land is that of the sons, the daughters will have no right therein at all. However, if the land is bought partially with the sons' money, the daughters will have no right in the part that was bought by the sons' money. However, if the money that bought the land was from the parents, it will be obligatory to
give all children equally. This is based on the general purport of the Hadith of the Prophet (peace be upon him):
Be afraid of Allah, and be just to your children.
The same applies to the part of the land that was bought by the parents' money if the land was bought partially by them. (Part No. 16; Page No. 196) May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
