These (disbelievers) ask you about the Last Hour: ‘When will it take place?’ Say: ‘Knowledge of it rests with my Lord alone; none but He (Allah) will manifest it at its (appointed) time. It is (seemingly) heavy on (the residents of) the heavens and the earth (due to the horror of its adversities and intensities). It will occur to you all of a sudden (accidentally).’ They ask you (in such a manner) as if you are engaged in its pursuit! Say: ‘Knowledge of it is only with Allah, but most people do not know (this fact).’
