Is it permissible to obtain a certificate of experience for a fee in order to enroll in a training course, knowing that success in it depends on personal effort?

It is not permissible to buy a certificate, due to the deliberate lying that results from it, as the Prophet, peace and blessings be upon him, said: "Indeed, lying leads to immorality, and immormorality leads to the Fire. And a man keeps on lying until he is written before Allah as a liar." It also entails cheating, as the Prophet, peace and blessings be upon him, said: "Whoever cheats is not one of us." Furthermore, it involves bearing false witness, as the Prophet, peace and blessings be upon him, said: "Shall I not tell you about the greatest of major sins?" They said: "Yes, O Messenger of Allah!" He said: "Associating partners with Allah, and disobedience to parents." He then sat up, after he had been reclining, and said: "And false witness or false speech!" The Messenger of Allah, peace and blessings be upon him, kept repeating it until we wished he would stop.
