Is it permissible, from a Sharia perspective, for someone suffering from obsessive-compulsive thoughts related to the rights of others, particularly in financial dealings, to consider themselves as having fulfilled these rights, based on the noble verse: "Indeed, Allah does not change what is in a people until they change what is in themselves"?

Being cautious regarding people's rights is a religious requirement, as long as it does not reach the point of obsessive doubt. There is no blame upon you concerning the doubt that arose regarding your certainty in the first five points, nor in the sixth point. As for the matter of the female and male doctors, you must return their right to them as long as their truthfulness has become clear to you. In the ninth point, you must go back to the shop owner to verify if he has a right, and if he claims a right with evidence or if you predominantly believe he is truthful, then pay him his right. Your refusal to accept a gift from the cashier and others is not blameworthy; rather, it is religiously required if he is not paying the right on your behalf and is not authorized to act.
