Is it permissible to seek assistance from the House Repair Committee to repair my father's house, given that my mother owns two houses, one of which is still under construction and for which she is paying installments?

There is no harm in requesting the renovation and finishing of a house from the responsible authority. However, the required information must be provided accurately, without deception or trickery. The important thing is to adhere to truthfulness and avoid forbidden cheating and deception, as the Prophet, peace and blessings be upon him, said: "Whoever cheats us is not of us."
