Tafsir of Al-Jinn 72:15

Surah Al-Jinn (The Jinn): (Verse 15)

وَأَمَّا الْقَاسِطُونَ فَكَانُوا لِجَهَنَّمَ حَطَبًا (And as for the deviators, they will be fuel for Hell.)

The First Inquiry: Why is the punishment of the deviators (Al-Qasitun) mentioned, while the reward of the believers is not mentioned?

The Answer: The reward of the believers is indeed mentioned. It is in His saying, the Exalted: {تَحَرَّوْا رَشَدًا} (Seek guidance/right conduct) (Al-Jinn: 14). This means they sought a great guidance whose true extent only God Almighty can comprehend. Such a thing (comprehending the reward) can only be realized in the context of a reward.

The Second Inquiry: The Jinn were created from fire; how, then, can they become fuel for the Fire (Hell)?

The Answer: Although they were created from fire, they have changed from that original state and have become like flesh and blood. It is said that this is the end of Al-Hasan's discourse on this matter.

{وَلَوِ اسْتَقَامُوا عَلَى الطَّرِيقَةِ لَأَسْقَيْنَاهُم مَّاءً غَدَقًا} (And if they had remained straight upon the way, We would have given them abundant water to drink.)

{لِنَفْتِنَهُمْ فِيهِ ۚ وَمَن يُعْرِضْ عَن ذِكْرِ رَبِّهِ يَسْلُكْهُ عَذَابًا صَعَدًا} (To test them therein. And whoever turns away from the remembrance of his Lord, He will make him enter a severe torment.)
