Tafsir of Al-Hajj 15
مَن كَانَ يَظُنُّ أَن لَّن يَنصُرَهُ ٱللَّهُ فِى ٱلدُّنْيَا وَٱلْـَٔاخِرَةِ فَلْيَمْدُدْ بِسَبَبٍ إِلَى ٱلسَّمَآءِ ثُمَّ لْيَقْطَعْ فَلْيَنظُرْ هَلْ يُذْهِبَنَّ كَيْدُهُۥ مَا يَغِيظُ
Whoever should think that Allāh will not support him [i.e., Prophet Muḥammad (ﷺ)] in this world and the Hereafter - let him extend a rope to the ceiling, then cut off [his breath], and let him see: will his effort remove that which enrages [him]?
Tafsir Ibn Kathir (abridged)
Hafiz Ibn Kathir · English· Passage 14–15
The Reward of the Righteous
The mention of the misguided who are doomed is followed by mention of the righteous who are blessed. They are those who believe firmly in their hearts and confirm their faith by their actions, doing all kinds of righteous deeds and avoiding evil actions. Because of this, they will inherit dwellings in the lofty ranks of the gardens of Paradise. So Allah tells us that He sends those astray and guides these, and says:
إِنَّ اللَّهَ يَفْعَلُ مَا يُرِيدُ
(Verily, Allah does what He wills.)
