Is it permissible to marry with the intention of cohabitation for a specific period due to inability to bear expenses and fear of falling into zina (unlawful sexual intercourse)? And if not permissible, what should one do?

Temporary marriage for a specified period in the contract (Nikah (definition) al-Mut'ah) is forbidden and invalid. As for a legitimate marriage in which no duration is mentioned, but the husband intends to divorce in the future, its ruling is disputed, and the majority validate it. It is recommended to enter into a permanent legitimate marriage and rely on Allah for sustenance, for Allah provides for those who marry. And whoever is unable to marry should practice chastity and fast, avoid places of temptation, strengthen their connection with Allah, associate with righteous people, and occupy their time with beneficial deeds.
