What can you tell us about the vision granted to Allah's Apostle Muhammad (peace be upon him) concerning the journey through the heavens and the cursed tree of Az-Zaqqum?
 Narrated Ibn `Abbas:                     Regarding: 'And We granted the vision (Ascension to the Heaven "Miraj") which We showed you (O Muhammad as an actual eye witness) but as a trial for mankind.' (17.60) It was an actual eyewitness which was shown to Allah's Apostle during the night he was taken on a journey (through the heavens). And the cursed tree is the tree of Az-Zaqqum (a bitter pungent tree which grows at the bottom of Hell).
