They ask you about the hour, when will be its taking place? Say: The knowledge of it is only with my Lord; none but He shall manifest it at its time; it will be momentous in the heavens and the earth; it will not come on you but of a sudden. They ask you as if you were solicitous about it. Say: Its knowledge is only with Allah, but most people do not know.

And We did not create the heavens and the earth and what is between them two but in truth; and the hour is most surely coming, so turn away with kindly forgiveness.

And if Allah had destroyed men for their iniquity, He would not leave on the earth a single creature, but He respites them till an appointed time; so when their doom will come they shall not be able to delay (it) an hour nor can they bring (it) on (before its time).

And Allah's is the unseen of the heavens and the earth; and the matter of the hour is but as the twinkling of an eye or it is higher still; surely Allah has power over all things.

And those who disbelieve say: The hour shall not come upon us. Say: Yea! by my Lord, the Knower of the unseen, it shall certainly come upon you; not the weight of an atom becomes absent from Him, in the heavens or in the earth, and neither less than that nor greater, but (all) is in a clear book

And blessed is He Whose is the kingdom of the heavens and the earth and what is between them, and with Him is the knowledge of the hour, and to Him shall you be brought back.

And Allah's is the kingdom of the heavens and the earth; and on the day when the hour shall come to pass, on that day shall they perish who say false things.
