If among one's daughters there is one who has a less standard of living, is it permissible for one to allocate a gift for her?

Q: My daughter earns less than her sisters, and her husband is also poor. His salary does not exceed 2,000 riyals, while the husbands of her sisters are well-off. Her husband has an old car that does not adequately serve them. I want to buy a car for my daughter and her husband because they owe a long-term debt on the home they built, in addition to their children and the orphans of his deceased brother. While the financial conditions of her sisters are better than hers, does this disagree with the Hadith of Allah's Messenger (peace be upon him): Be afraid of Allah, and be just to your children. Or not?

A: If the reality is as you have mentioned, there is nothing wrong in purchasing a car for your daughter's husband or helping him to buy it. As for your daughter, you should not favor her with something over her sisters, because her sustenance is incumbent on her husband.May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
