Surely Allah is He with Whom is the knowledge of the hour, and He sends down the rain and He knows what is in the wombs; and no one knows what he shall earn on the morrow; and no one knows in what land he shall die; surely Allah is Knowing, Aware.

Men ask you about the hour; say: The knowledge of it is only with Allah, and what will make you comprehend that the : hour may be nigh.

Allah it is Who revealed the Book with truth, and the balance, and what shall make you know that haply the hour be nigh?

And when it was said, Surely the promise of Allah is true and as for the hour, there is no doubt about it, you said: We do not know what the hour is; we do not think (that it will come to pass) save a passing thought, and we are not at all sure.
