(Muhammad Assad)
22:15 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. 22:15
(Yousaf Ali)
22:15 If any think that Allah will not help him (His Messenger. in this world and the Hereafter, let him stretch out a rope to the ceiling and cut (himself) off: then let him see whether his plan will remove that which enrages (him)!22:15
