﴿ 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 lo! We said unto thee, [O Prophet:] "Behold, thy Sustainer encompasses all mankind [within His knowledge and might]: and so We have ordained that the vision which We have shown thee -as also the tree [of hell,] cursed in this Qur'an - shall be but a trial for men. Now [by Our mentioning hell] We convey a warning to them: but [if they are bent on denying the truth,] this [warning] only increases their gross, overweening arrogance."”

(�and (likewise) the Accursed Tree in the Qur�an�) [17:60]. Isma�il ibn �Abd al-Rahman ibn Ahmad al-Wa�iz informed us> Muhammad ibn Muhammad al-Faqih> Muhammad ibn al-Husayn al-Qattan> Ishaq ibn �Abd Allah ibn Zurayr> Hafs ibn �Abd al-Rahman> Muhammad ibn Ishaq> Hakim ibn �Abbad ibn Hunayf> �Ikrimah> Ibn �Abbas that he said: �When the tree of al-Zaqqum was mentioned in the Qur�an [37:62; 44:43 and 56:52], the Quraysh were threatened with it. Abu Jahl said: �Do you know what this Zaqqum, with which Muhammad threatens you, is?� They said: �No!� He said: �Meat and broth with cream. By Allah, if he let us put our hands on it we will devour it!� Allah, glorious and exalted is He, revealed (�and (likewise) the Accursed Tree in the Qur�an�) saying: this tree is repulsive (We warn them, but it increaseth them in naught save gross impiety)�.
