Is it permissible to take a sum of money in exchange for transferring the sponsorship of a foreign worker to another sponsor?

You have the choice between canceling the sponsorship or transferring it to someone else. Transferring it is preferable if it benefits Muslim workers and does not harm you; otherwise, canceling it is preferable. As for taking money in exchange for relinquishing sponsorship, this falls under the category of "selling one's influence," and we have clarified its ruling in Fatwa numbers 32291 and 32454.
