“They ask you about the Hour (of Resurrection) when it will set in.

“They ask you about the Hour (of Resurrection) when it will set in. Say: ‘Its knowledge is only with my Lord. None but He can manifest it at its time. Heavy is it in the heavens and the earth. It will not overtake you but suddenly’. They ask you, as if you were well-informed of it.

Say: ‘The knowledge of it is only with Allah, but most people do not know’.”*** The infidels of Quraysh sent a number of persons to the scholars of the Jews in order to learn some difficult questions so that when they would ask them from the Prophet (S) he could not give any answer to them and they might condemn him. One of these questions was that they asked about the exact time of the occurrence of Resurrection.

The Qur’ānic term /’ayyān/, mentioned in this verse, has been used for asking the time.
