Is it permissible to continue helping students with their graduation projects, given an inner feeling that they might not be honest about informing their supervisors? And does the work become forbidden if the students do not watch the recorded explanation that was a condition for the work to be permissible? What is the ruling on works completed before knowing the fatwas, and how can one dispose of the money earned from them?

Preparing academic assignments or graduation projects for students, presenting them as their own work, is forbidden (haram). This is because it constitutes aiding in cheating, lying, and claiming something that one has not been given. An exception to this is providing assistance with formal aspects, such as typing, formatting, preparing indexes, and gathering sources, as these are not part of the original evaluation. As for the earnings you gained from preparing forbidden projects before you were aware of the ruling, it is hoped that there is no sin upon you, and you are not required to dispose of what you acquired.
