Allah’s Promise

He never fails in His promise.

13:31Had it been possible for a Lecture to cause the mountains to move, or the earth to be torn asunder, or the dead to speak, (this Qur'an would have done so). Nay, but Allah's is the whole command. Do not those who believe know that, had Allah willed, He could have guided all mankind? As for those who disbelieve, disaster ceaseth not to strike them because of what they do, or it dwelleth near their home until the threat of Allah come to pass. Lo! Allah faileth not to keep the tryst.

30:6It is a promise of Allah. Allah faileth not His promise, but most of mankind know not.

39:20But those who keep their duty to their Lord, for them are lofty halls with lofty halls above them, built (for them), beneath which rivers flow. (It is) a promise of Allah. Allah faileth not His promise.
