Sahih al-Bukhari 3888
Narrated Ibn `Abbas:
Regarding the Statement of Allah" 
"And We granted the vision (Ascension to the heavens) which We made you see (as an actual eye 
witness) was only made as a trial for the people." (17.60) 
Ibn `Abbas added: The sights which Allah's Messenger (ﷺ) was shown on the Night Journey when he was 
taken to Bait-ulMaqdis (i.e. Jerusalem) were actual sights, (not dreams). And the Cursed Tree 
(mentioned) in the Qur'an is the tree of Zaqqum (itself) .
حَدَّثَنَا الْحُمَيْدِيُّ، حَدَّثَنَا سُفْيَانُ، حَدَّثَنَا عَمْرٌو، عَنْ عِكْرِمَةَ، عَنِ ابْنِ عَبَّاسٍ ـ رضى الله عنهما ـ فِي قَوْلِهِ تَعَالَى ‏{‏وَمَا جَعَلْنَا الرُّؤْيَا الَّتِي أَرَيْنَاكَ إِلاَّ فِتْنَةً لِلنَّاسِ‏}‏ قَالَ هِيَ رُؤْيَا عَيْنٍ، أُرِيَهَا رَسُولُ اللَّهِ صلى الله عليه وسلم لَيْلَةَ أُسْرِيَ بِهِ إِلَى بَيْتِ الْمَقْدِسِ‏.‏ قَالَ وَالشَّجَرَةَ الْمَلْعُونَةَ فِي الْقُرْآنِ قَالَ هِيَ شَجَرَةُ الزَّقُّومِ‏.‏
