Sunan Ibn Majah Book 37, Hadith 4325

حَدَّثَنَا مُحَمَّدُ بْنُ بَشَّارٍ، حَدَّثَنَا ابْنُ أَبِي عَدِيٍّ، عَنْ شُعْبَةَ، عَنْ سُلَيْمَانَ، عَنْ مُجَاهِدٍ، عَنِ ابْنِ عَبَّاسٍ، قَالَ قَرَأَ رَسُولُ اللَّهِ ـ صلى الله عليه وسلم ـ ‏{يَا أَيُّهَا الَّذِينَ آمَنُوا اتَّقُوا اللَّهَ حَقَّ تُقَاتِهِ وَلاَ تَمُوتُنَّ إِلاَّ وَأَنْتُمْ مُسْلِمُونَ }‏ ‏"‏ وَلَوْ أَنَّ قَطْرَةً مِنَ الزَّقُّومِ قُطِرَتْ فِي الأَرْضِ لأَفْسَدَتْ عَلَى أَهْلِ الدُّنْيَا مَعِيشَتَهُمْ فَكَيْفَ بِمَنْ لَيْسَ لَهُ طَعَامٌ غَيْرُهُ ‏"‏ ‏.‏

It was narrated from Ibn ‘Abbas that the Messenger of Allah (ﷺ) recited:“O you who believe! Have fear of Allah as is His due, and die not except as Muslims. [3:102] (Then he said): ‘If a drop of Zaqqum were to be dropped on the earth, it would ruin the livelihood of the people of this world, so how about those who have no food other than it (i.e. Zaqqum)?’”
