quran:37:62 –

Is Paradise a better accommodation or the tree of zaqqum?  

Is that, which is mentioned to them, a better hospitality (nuzul, denotes what is prepared for one who is being received as a guest and so forth) or the Zaqqūm tree, that is prepared for the inhabitants of the Fire — it is the vilest and most bitter tree of the Tihāma region, which God causes to grow in the Fire, as will be stated shortly.
القرآن:٣٧:٦٢ –

أَذَٰلِكَ خَيْرٌ نُزُلًا أَمْ شَجَرَةُ الزَّقُّومِ  

{أذلك} المذكور لهم {خير نزلا} وهو ما يعدّ للنازل من ضيف وغيره {أم شجرة الزقوم} المعدة لأهل النار وهي من أخبث الشجر المرّ بتهامة ينبتها الله في الجحيم كما سيأتي.
