Is the Prophet Muhammad (peace be upon him) in Hell, and will all Muslims, Jews, Christians, and followers of other religions enter it, according to what is stated in prophetic hadiths such as the Hadith of the Sirat in Sahih Al-Bukhari and others?

When a person's life ends, their soul departs from their body but does not perish. It remains wherever Allah wills, either in bliss or torment, until the Hour. The souls of the prophets are in the highest 'Illiyyin in the intermediate life (barzakh (definition)), and their bodies are preserved in their graves, not decaying.

After the second blowing of the Trumpet, people will rise from their graves for accountability. And His (Allah's) saying: ﴿وَإِنْ مِنْكُمْ إِلَّا وَارِدُهَا﴾ (And there is none of you but will pass over it [Hell]) means that everyone will pass over the Sirat (bridge) above Hell, some will be saved and some will fall. The righteous will be saved, and the wrongdoers will be tormented. The speed of passing will vary according to deeds, and the prophets will be the fastest to pass, for the Fire will not touch them, because Allah Almighty has forbidden the Fire to consume the bodies of the prophets except for the place of prostration. So, the Fire consumes every son of Adam except the mark of prostration. "Passing over" (al-wurud) does not mean "entering" the Fire, but rather passing over it. The prophets and the righteous are kept away from the heat and torment of the Fire.
