Is it permissible to marry Islamically and customarily—without official registration—to prevent the cessation of the pension necessary for supporting her daughters?

It is not permissible to circumvent the conditions for receiving the pension imposed by the state, as it involves forgery, deception, and consuming wealth unjustly. If the pension is disbursed to a widow or divorcee and ceases upon marriage, it is not permissible to circumvent this by not registering the marriage contract. This circumvention involves several corruptions, including: consuming public funds unjustly, which is unlawful gain; and undermining the rights of the spouses and children due to the lack of marriage documentation, which could lead to a man rejecting his wife or vice versa. What the questioner seeks from this circumvention to obtain the pension is not permissible for her, and the inadequacy of the husband's pension is not an excuse to feed the children unlawful wealth. The questioner should fear Allah and be patient by remaining unmarried for her parents' pension to continue, or she should marry and economize in spending on her daughters, helping them as much as she can.
