What is the ruling on one who fears the time will expire if he performs ghusl?

Question:
If he fears the time will expire by performing ghusl?

Answer:
If he is awake and has been negligent, he prays; he performs ghusl and prays.
As for if he is sleeping, no, even if the time expires; because when the Messenger (peace and blessings be upon him) slept through the prayer, he delayed it until they performed wudu and prayed. He is excused, and the Prophet (peace and blessings be upon him) said: .
As for a person who is awake, he has no right to delay; rather, he prays according to his condition.
Q: If he is awake and delays?
A: It is not permissible for him to delay; the one who is awake prays within the time.
Q: If he delayed it and fears the time will expire if he performs ghusl?
A: It appears that he prays with tayammum in this case and does not delay, if seeking wudu or seeking ghusl causes the time to be missed, unless he is sleeping. He is excused even if the time is missed, one who sleeps through the prayer or forgets it, if he is sleeping or forgetting.
