What is the explanation of the Hadith: "So Allah should not demand anything of you from His protection; for whoever He demands anything from His protection, He will apprehend him and then cast him on his face into the fire of Hell"?

The meaning of the Hadith is that the Prophet (peace and blessings of Allah be upon him) warns people against harming a Muslim who performs the Fajr prayer, and he clarifies that whoever performs it has entered into the guarantee, protection, and security of Allah. This is the meaning of his saying: "Then he is under the protection of Allah."
