Is it obligatory for the father to be just between his sons and daughters in gifts?

Question : Hello, yes, a moment. Peace be upon you. If you please, may I ask a question? Yes, regarding the father, if he gives the children, O Shaykh, sums of money to the sons during his lifetime, is it obligatory for him to give the daughters the same amount equally?

Answer : To be just between the children in gifts, based on the saying of the Prophet (peace and blessings be upon him) and justice is to give the male the share of two females. So if he gives the female one dirham, he gives the male two dirhams, and if he gives the male four dirhams, he gives the female two dirhams.
Because there is no division more just than the division of Allah (Mighty and Majestic), and Allah the Exalted said: He has appointed for you This is regarding voluntary gifts. As for maintenance, justice among them is to give each one what he needs. So if he has two sons, one is young and the other is studying, and the second needs school supplies, he gives them to him and does not give them to the young son who is not studying.
Justice in maintenance is to give each one what he needs, and justice in voluntary gifts is to give the male the share of two females. This includes if he has sons, one of whom has reached the age of marriage and asked for marriage, his father must marry him off if he is able. He does not give the brothers the same unless they reach the age of marriage and ask for marriage, in which case he marries them off as he married the first, because marriage is part of maintenance. So whoever among them needs marriage, he marries him off, and he does not give the others the same unless they reach the age of marriage and ask for marriage, in which case he marries them off as he married their brother. Here is a matter in which some people err.
It is that there are young and older sons. He marries off the older ones. Then he bequeaths after his death to marry off the young ones from the estate. This bequest is invalid and not permissible. Because he bequeathed to an heir more than his right. And the Prophet (peace and blessings be upon him) said:
It is said to this man: You have now married off the older ones, so when the young ones reach their age, marry them off. If they reach that age during your lifetime, marry them off from your wealth. If you die before they reach that age, they have nothing from you, and it is not permissible for you to bequeath anything to them. May Allah reward you.
