What is the ruling regarding a mother depriving her male children of her wealth, despite their need for assistance in marriage, and allocating all her money to her daughters?

The Sharia commanded justice among children in gifts and endowments. This justice is obligatory for the mother just as it is for the father, and it is fulfilled by giving the male the same as the female. Equality is achieved by giving the remaining children the same as what one of them was given, or by returning what was given. It is obligatory for the mother to marry off her children who are in need if she is well-off, because safeguarding the chastity of those for whom maintenance is obligatory is a duty.
