Is it permissible for a person to combine two prayers if he is in a state of extreme exhaustion and needs sleep?

Question:
He says: Honorable Shaykh, may Allah grant you success, is it permissible for a person to combine two prayers if he is in a state of extreme exhaustion and needs sleep, and his family may wake him and try, but he is unaware of himself due to the exhaustion? So, is it permissible for him to combine?

Answer:
No, sleep is not a valid reason for combining. But what is the cause of the exhaustion? He should leave the cause that led to his exhaustion. Perhaps he stays up late on the internet or on television, and that is what caused the exhaustion. So he should leave the causes that caused his exhaustion. He does things that are not permissible, and then he also manipulates the prayer. This is not permissible. Yes. As for if the exhaustion is due to illness, he combines. If the exhaustion is due to illness, he combines. But if the exhaustion is due to frivolous staying up late, then it is not permissible for him to combine. Yes.
