Ibn 'Abbas commented on Allah, the Most High, saying:

And We made not the vision which We showed but a trial for mankind (17:60). He said: "It is the vision he saw with his eyes, on the night the Prophet ﷺ was taken on the journey to Bait Al-Maqdis. And the accursed tree in the Qur'an (17:60). He said: "It is the Zaqqum tree."

حَدَّثَنَا ابْنُ أَبِي عُمَرَ، حَدَّثَنَا سُفْيَانُ، عَنْ عَمْرِو بْنِ دِينَارٍ، عَنْ عِكْرِمَةَ، عَنِ ابْنِ عَبَّاسٍ، فِي قَوْلِهِ: ( ومَا جَعَلْنَا الرُّؤْيَا الَّتِي أَرَيْنَاكَ إِلاَّ فِتْنَةً لِلنَّاسِ ) قَالَ هِيَ رُؤْيَا عَيْنٍ أُرِيَهَا النَّبِيُّ ﷺ لَيْلَةَ أُسْرِيَ بِهِ إِلَى بَيْتِ الْمَقْدِسِ . قَالَ : (وَالشَّجَرَةَ الْمَلْعُونَةَ فِي الْقُرْآنِ ) هِيَ شَجَرَةُ الزَّقُّومِ . قَالَ هَذَا حَدِيثٌ حَسَنٌ صَحِيحٌ .
