The ruling on combining two prayers due to exhaustion and the need for sleep

Question:
May Allah reward you with good. Among her questions, Honorable Shaykh Salih, she asks: What is the ruling on a person advancing a prayer from the five, such as praying the midday prayer and then praying the afternoon prayer immediately after, due to extreme fatigue and exhaustion, and an urgent need for sleep? May Allah reward you?

Answer:
This is not permissible. Delaying a prayer from its time to the time of the next prayer is forbidden, and the prayer is invalid. Allah the Exalted said: , meaning that it is obligatory at specific times. Therefore, the prayer must be performed in its time, whether at the beginning, the middle, or the end of it. Performing it at the beginning is better, except for the night prayer, where delaying it is better until the middle of the night or until one-third of the night. Combining two prayers is only permissible in cases of excuse, such as illness, travel, or combining the night prayer due to rain. These are the excuses that permit combining. As for combining for the sake of sleep, this is not permissible. Each prayer must be prayed in its time. It is obligatory for the sleeper to wake up by appointing someone to wake him or setting an alarm to wake him. As for sleeping with the intention that he will pray whenever he wakes up, this is forbidden and not permissible. Yes.
