Is it permissible for a man to claim separation from his wife to obtain financial support from the state, knowing that this practice is common among Muslims in Western countries due to low income and high living costs?

My advice to the questioner is to adhere to truthfulness in all circumstances and to fulfill the conditions required for the permissibility of benefiting from social security, based on the hadith (definition): "Muslims are bound by their conditions." He must also not betray or deceive the people, as he entered their country under a covenant and a guarantee of safety. Jurists have unanimously agreed that if a Muslim enters a land of war under a guarantee of safety, it is forbidden for him to expose any of their lives, wealth, or women to harm. If this is the case for lands of war, then what about other countries? The involvement of Muslims in such dealings harms Islam and alienates people from it if they discover its adherents resorting to tricks and lies to acquire money unjustly.
