Is it permissible for the husband to spend on himself and his minor children from the pension allocated to them by the pension fund after his wife's death, knowing that he is employed and his salary is sometimes insufficient?

It is permissible for a father to spend on his children from their own wealth, whether it is from their mother's inheritance or otherwise, because their maintenance is not obligatory upon him if they possess wealth that suffices them, even if they are young. However, if a father spends on them from his own wealth while they possess wealth, this is considered an act of righteousness and kindness for which he will be rewarded. His obligation to maintain them only arises if they have no wealth or ability to earn.
