Tafsir: Al-A'raf 7:187

They ask you ˹O Prophet˺ regarding the Hour, “When will it be?” Say, “That knowledge is only with my Lord. He alone will reveal it when the time comes. It is too tremendous for the heavens and the earth and will only take you by surprise.” They ask you as if you had full knowledge of it. Say, “That knowledge is only with Allah, but most people do not know.”
