Surat Al-Hajj (The Pilgrimage) - الحج

مَن كَانَ يَظُنُّ أَن لَّن يَنصُرَهُ ٱللَّهُ فِى ٱلدُّنْيَا وَٱلْءَاخِرَةِ فَلْيَمْدُدْ بِسَبَبٍ إِلَى ٱلسَّمَآءِ ثُمَّ لْيَقْطَعْ فَلْيَنظُرْ هَلْ يُذْهِبَنَّ كَيْدُهُۥ مَا يَغِيظُ ﴿١٥﴾

Whoever thinks that Allah will not assist him in this life and the hereafter, let him stretch a rope to the ceiling, then let him cut (it) off, then let him see if his struggle will take away that at which he is enraged.
