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

“If anyone thinks that God will not succour him in this world and in the life to come, let him reach out unto heaven by any [other] means and [thus try to] make headway: and then let him see whether this scheme of his will indeed do away with the cause of his anguish.”
