While the Isra did happen (17:1, 53:1-18), fairytales associated with it do not make any sense when scrutinized under Quran's light. First I will sum up this story, and then I will take a look at it Quranicly.
This story is usually called in Muslim literature the story of al-isra'a and al-mi'raj or the prophet Muhammad quit night journey (al-isra'a) from Mecca to al-masjid al-aqsa (the farthest mosque) in Jerusalem, then his ascension to heaven (al-mi'raj) and his return in few minutes back to Mecca. They said it happened on 27th night of Rajab (the 7th lunar month) in 621 AD (Muhammad was then 50-year old).
