مَن كَانَ يَظُنُّ أَن لَّن يَنصُرَهُ ٱللَّهُ فِى ٱلدُّنْيَا وَٱلْءَاخِرَةِ فَلْيَمْدُدْ بِسَبَبٍ إِلَى ٱلسَّمَآءِ ثُمَّ لْيَقْطَعْ فَلْيَنظُرْ هَلْ يُذْهِبَنَّ كَيْدُهُۥ مَا يَغِيظُ
Whoso is wont to think (through envy) that Allah will not give him (Muhammad) victory in the world and the Hereafter (and is enraged at the thought of his victory), let him stretch a rope up to the roof (of his dwelling), and let him hang himself. Then let him see whether his strategy dispelleth that whereat he rageth!.
Surah Al-Hajj(22:15)
