وَإِذْ قُلْنَا لَكَ إِنَّ رَبَّكَ أَحَاطَ بِٱلنَّاسِ ۚ وَمَا جَعَلْنَا ٱلرُّءْيَا ٱلَّتِىٓ أَرَيْنَٰكَ إِلَّا فِتْنَةًۭ لِّلنَّاسِ وَٱلشَّجَرَةَ ٱلْمَلْعُونَةَ فِى ٱلْقُرْءَانِ ۚ وَنُخَوِّفُهُمْ فَمَا يَزِيدُهُمْ إِلَّا طُغْيَٰنًۭا كَبِيرًۭا
And (it was a warning) when we told thee: Lo! thy Lord encompasseth mankind, and We appointed the sight which We showed thee as an ordeal for mankind, and (likewise) the Accursed Tree in the Qur'an. We warn them, but it increaseth them in naught save gross impiety.
Surah Al-Israa(17:60)
