Sahih al-Bukhari Book 65, Hadith 238
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 Messenger (ﷺ) 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).
Regarding the Verse: 'Those whom they call upon (worship) (like Jesus the Son of Mary or angels etc.) desire (for themselves) means of access, to their Lord....' (17.57) (It was revealed regarding) some Jinns who used to be worshipped (by human beings). They later embraced Islam (while those people kept on worshipping them).
Abu Huraira said, "The Prophet (ﷺ) said, 'A prayer performed in congregation is twenty-five times more superior in reward to a prayer performed by a single person. The angels of the night and the angels of the day are assembled at the time of the Fajr (Morning) prayer." Abu Huraira added, "If you wish, you can recite:-- 'Verily! The recitation of the Qur'an in the early dawn (Morning prayer) is ever witnessed (attended by the angels of the day and the night).' (17.78)
