He gave more to the males than to the females then he died

Question

Praise be to Allah.

If a man has given his children a gift other than what he is
obliged to spend on their maintenance, he has to treat them fairly because
of the report narrated by al-Bukhaari (2587) and Muslim (1623) from
an-Nu‘maan ibn Basheer, who said: My father gave me some of his wealth and
my mother, ‘Amrah bint Rawaahah, said: I will not approve until you ask the
Messenger of Allaah (blessings and peace of Allah be upon him) to bear
witness. So my father went to the Prophet (blessings and peace of Allah be
upon him) to ask him to bear witness to my gift. The Messenger of Allaah
(blessings and peace of Allah be upon him) said to him: “Have you done this
for all your children?” He said: No. He said: “Fear Allaah and treat your
children fairly.” My father came back and took back the gift.

According to another report in Muslim (1623) The Messenger of
Allaah (blessings and peace of Allah be upon him) said: “O Basheer, do you
have any other children?” He said: Yes. He said: “Have you given to all of
them like you have given to this one?” He said: No. He said: “Then do not
ask me to bear witness for I will not bear witness to injustice.”

Ibn Qudaamah (may Allah have mercy on him) said: A man must
be fair in giving gifts to his children, and not single out one of them or
do anything to indicate that he prefers one of them over another. If he
singles out one of them for giving, or he shows that he prefer one over
another, then he is sinning, and he must treat them all fairly by means of
one of two things, either taking back what he gave to some in exclusion of
others, or giving to the others. Tawoos said: That is not permissible, not
even if you show preference to one by giving him a burned loaf of bread
(that you do not give to the others). This was also the view of Ibn
al-Mubaarak, and something similar was narrated from Mujaahid, and ‘Urwah.

If the children are both male and female, then treating them
fairly means giving each male the share of two females, because this is the
division that Allah has approved for His slaves in terms of inheritance.
This is the view of the Hanbalis.

However the majority are of the view that males and females
should be given equal shares when giving gifts.

Ibn Qudaamah (may Allah have mercy on him) said: Once this is
proven, the fair giving that is recommended is to share among them in
accordance with the way in which Allah has ordained inheritance to be shared
out. So each male should be given the share of two females. This is the view
of ‘Ata’, Shurayh, Ishaaq and Muhammad ibn al-Hasan. Shurayh said to a man
who shared out his wealth among his children: Refer to the division of the
estate as mentioned in the Book of Allah and share it out accordingly. ‘Ata’
said: They (the salaf) did not share out wealth but in accordance with the
Book of Allah, may He be exalted.

Abu Haneefah, Maalik, ash-Shaafa‘i and Ibn al-Mubaarak said:
The female is to be given the same as the male, because the Prophet
(blessings and peace of Allah be upon him) said to Basheer ibn Sa‘d: “Treat
them fairly (equally)” and he explained that by saying: “Would you like them
all to honour you equally?” He said: “Yes.” He said: “Then treat them fairly
(equally).” And the daughter is like the son in terms of the duty to honour
the parents, and the same applies to giving gifts to her. It was narrated
that Ibn ‘Abbaas said: The Messenger of Allah (blessings and peace of Allah
be upon him) said: “Treat your children fairly (equally) in giving gifts;
and if I were to have given precedence to anyone, I would have given
precedence to women over men.” Narrated by Sa‘eed in his Sunan. And
because it is a gift given during one’s lifetime, so male and female are to
be treated equally, as is the case with regard to spending on maintenance
and clothing.

But we say: Allah, may He be exalted, has explained how
wealth is to be divided among them and He has given the male a share equal
to that of two females. So it should be divided in accordance with the way
in which it is to be divided after death, i.e., inheritance.

This is confirmed by the fact that a gift given to children
is like hastening to pass on wealth before one’s death, and is similar to
what happens after death. Therefore it should be divided in accordance with
the way in which it is to be divided after death. This is like when one pays
zakaah before it becomes due: it is to be paid in the same manner as it
would be paid after it becomes due. Moreover the male is in greater need of
wealth than the female because when they get married, the dowry, maintenance
and maintenance of the children are the responsibility of the male, and the
female is benefitting from all that; hence giving precedence to the male is
more appropriate because his need is greater. Allah, may He be exalted, has
ordained the manner in which the estate is to be divided and He has given
precedence to the male for the reasons referred to above. The same reason is
applicable to gifts given during a person’s lifetime.

End quote from al-Mughni, 5/389

If the father gave more to some than they were entitled to
during his lifetime, then he died, the children should correct this division
and establish justice. They should complete the daughters’ shares so that
the daughters will have half of what the males have. Then whatever is left
over of the estate should be shared out after that.

Based on that, the sons mentioned have to give each of their
sisters 45 million riyals before dividing the estate. If they do not do
that, they will be sinning, acting unjustly and consuming wealth
unlawfully.

And Allah knows best.
