Qur'an, At-Taghabun, "Surah" 64:11-12
No kind of calamity can occur, except by the leave of Allah: and if any one believes in Allah, (Allah) guides his heart (aright): for Allah knows all things.
So obey Allah, and obey His Messenger, but if ye turn back, the duty of Our Messenger is but to proclaim (the Message) clearly and openly.
