187th Ayah from Surah Al A'raf
Sahih International
They ask you, [O Muhammad], about the Hour: when is its arrival? Say, "Its knowledge is only with my Lord. None will reveal its time except Him. It lays heavily upon the heavens and the earth. It will not come upon you except unexpectedly." They ask you as if you are familiar with it. Say, "Its knowledge is only with Allah, but most of the people do not know."
Abdul Haleem
They ask you [Prophet] about the Hour, ‘When will it happen?’ Say, ‘My Lord alone has knowledge of it: He alone will reveal when its time will come, a time that is momentous in both the heavens and earth. All too suddenly it will come upon you.’ They ask you about it as if you were eager [to find out]. Say, ‘God alone has knowledge of [when it will come], though most people do not realize it.’
Mohsin Khan/Hilali
They ask you about the Hour (Day of Resurrection): "When will be its appointed time?" Say: "The knowledge thereof is with my Lord (Alone). None can reveal its time but He. Heavy is its burden through the heavens and the earth. It shall not come upon you except all of a sudden." They ask you as if you have a good knowledge of it. Say: "The knowledge thereof is with Allah (Alone) but most of mankind know not."
Taqi Usmani
They ask you about the Hour (i.e. the Doomsday), “When is it due to happen?” Say, “Its knowledge is only with my Lord. No one can unfold it except He at its time. It shall weigh heavy in the heavens and the earth. It shall not come upon you but suddenly.” They ask you as if you were aware of it. Say, “Its knowledge is only with Allah, but most of the people do not know.”
