Is it permissible to draw up a fictitious rental contract for a widow with orphaned children in order to change her place of residence and facilitate the disbursement of her disabled son's salary, on condition that the contract be annulled after the purpose is achieved?

Lying is forbidden except out of necessity or an urgent need. If a woman needs money to support her disabled child and his siblings, and she is harmed by not obtaining it, it is permissible for her to claim a change of residence to get the money. Lying is permissible to achieve a permissible objective that cannot be obtained otherwise. Lying becomes obligatory if the objective is obligatory, such as protecting a Muslim from an oppressor. It is preferable to use tawriyah (ambiguity) if possible; otherwise, explicit lying is permissible in these cases.
