﴿ يَسْـَٔلُونَكَ عَنِ ٱلسَّاعَةِ أَيَّانَ مُرْسَىٰهَا ۖ قُلْ إِنَّمَا عِلْمُهَا عِندَ رَبِّى ۖ لَا يُجَلِّيهَا لِوَقْتِهَآ إِلَّا هُوَ ۚ ثَقُلَتْ فِى ٱلسَّمَٰوَٰتِ وَٱلْأَرْضِ ۚ لَا تَأْتِيكُمْ إِلَّا بَغْتَةًۭ ۗ يَسْـَٔلُونَكَ كَأَنَّكَ حَفِىٌّ عَنْهَا ۖ قُلْ إِنَّمَا عِلْمُهَا عِندَ ٱللَّهِ وَلَٰكِنَّ أَكْثَرَ ٱلنَّاسِ لَا يَعْلَمُونَ ﴾

“THEY WILL ASK thee [O Prophet] about the Last Hour: "When will it come to pass?" Say: "Verily, knowledge thereof rests with my Sustainer alone. None but He will reveal it in its time. Heavily will it weigh on the heavens and the earth; [and] it will not fall upon you otherwise than of a sudden." They will ask thee - as if thou couldst gain insight into this [mystery] by dint of persistent inquiry! Say: "Knowledge thereof rests with my Sustainer alone; but [of this] most people are unaware."”

(They) the people of Mecca (ask thee) O Muhammad (of the (destined) Hour) about the timing and occurrence of the Last Hour, (when will it come to port. Say: Knowledge thereof) the knowledge of its timing and occurrence (is with my Lord only) is from my Lord. (He alone will manifest it at its proper time) none but He manifests its occurrence and timing. (It is heavy in the heavens and the earth) the knowledge of its occurrence and timing is heavy on the dwellers of the heavens and earth. (It cometh not to you save unawares) except all of a sudden. (They question thee) O Muhammad about the Hour (as if thou couldst be well informed thereof) as if you have knowledge of its timing; it is also said that this means: as if you are ignorant of it; as it is said that this means: as if you are oblivious to it. (Say) O Muhammad: (Knowledge thereof) knowledge of its occurrence and timing (is with Allah only) from Allah only, (but most of mankind) the people of Mecca (know not) nor believe in it.
