What is the Islamic legal ruling concerning a man who administratively divorced his wife (i.e., obtained an official divorce certificate without uttering the divorce pronouncement) with the aim of marrying a foreign woman to obtain residency, and then divorces the second wife and returns to the first?

The rulings on marriage (nikah) and divorce (talaq) must not be trifled with, for they constitute a solemn covenant and possess profound jurisprudential rulings. It is forbidden to use them as a means to achieve worldly gains, such as obtaining residency or a license, as this constitutes toying with the verses of Allah and trifling with His sacred limits. Fictitious marriages and divorces are prohibited. The effects of a valid marriage take place immediately upon the conclusion of the contract, and divorce occurs immediately upon its pronouncement. The sin is compounded if the intention behind it is to commit a forbidden act. Furthermore, marrying with the intention of obtaining residency and then divorcing is forbidden and considered deception and falsehood, in addition to seeking residency in lands of disbelievers, which is prohibited except out of necessity. Muslims must fear Allah concerning legal contracts and not use them as a means for forbidden worldly purposes.
