What is obligatory for a person if he sees that remaining in the lands of disbelief leads to a diminishment of his religion?

Question : But if someone says, "I went with the intention of preserving my faith and committing to staying upon my religion, but I noticed a decline in my religion in myself. Is it permissible for me to remain after I have seen this deficiency, or is it obligatory for me to return?"

Answer : The answer: It is obligatory to return, because preserving the religion is more important than preserving this world. This world does not last, but the religion lasts. The Hereafter is better than the first. Allah the Exalted says: And He said to His Prophet (peace and blessings be upon him): So if you see that your remaining in the lands of disbelief leads to a diminishment of your religion or the loss of your religion, it is obligatory for you to return, even if you lose half of your capital. Do not care about the loss that enters you in this world, for if Allah the Exalted knows from His servant the sincerity of intention, and the person leaves something for the sake of Allah the Exalted, then Allah will compensate him with something better than it.
