They ask you about the (final) Hour, (Resurrection)— When is its appointed time? Say: "Its knowledge is with my Lord (alone): No one except He can say when it will happen. Its burden was heavy through the heavens and the earth. Only, all of a sudden it will come to you." They ask you as if you were eager in search of it: Say: "Its knowledge is with Allah (alone), but most men do not know."
