Islam and Muhammad

by [deleted]

Don't some chapters in Quran like the one which describes Muhammad's 'journey to the heavens' from Jerusalem seem to be written after his death?

sln26

Can you explain what you mean? The chapters which reference the Isra and Mi'raj do so only in passing. There's actually very little mentioned in the Qur'an about it. Pretty much everything outside one or two things comes from Hadith literature, not Qur'an.
