Al-Hajj 22:15

The Pilgrimage · Medinan · Juz 17 · Page 333

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.
