Is what the wife requests from the husband—to create a savings account in the names of their two daughters to secure their future—considered permissible as a lawful gift, or is it a circumvention of legitimate inheritance laws? And will these amounts be exempt from the lawful division of the estate after the father's death, especially since the mother will become their guardian?

It is permissible for a Muslim to give as much of his wealth as he wishes to his children, intending to maintain kinship ties or to assist them. However, it is forbidden for the gift to be intended to disinherit other heirs, as this is a form of deception against the law of Allah. Ibn Qudamah said: "All stratagems are forbidden, not permissible in any matter of religion." The gift must fulfill its conditions of equality (among recipients), possession (by the recipient), and not being contingent upon the donor's death. If the son is young, the father acts on his behalf in taking possession. As for depositing money in a savings account or purchasing savings certificates, it is not permissible except in Islamic banks that adhere to Sharia regulations.
