35. They did not ask this question in order to know the time and date of Resurrection so that if they were told the year, the month, the day and time of its occurrence, they would accept it. But, in fact, they thought that Resurrection was impossible, and its occurrence remote from reason, and they asked this question in order to have an excuse for denying it. They meant to say: When will this strange story of Resurrection and gathering together, that you are telling us, materialize? What for has it been put off? Why don’t you make it appear forthwith so that we are assured of it? In this connection, one should understand that one can be certain of Resurrection only by rational arguments, and these have been elaborated at many places in the Quran. As for the date of its occurrence only an ignorant person could raise such a question about it, for even if it is told, it does not make any difference. The unbeliever would say: Well, when it does occur on the date you tell, I shall then believe in it; how can I believe today that it will actually occur on that very day? (For further explanation, see (E.N. 63 of Surah Luqman); (E.N. 116 of Surah Al-Ahzab); (E.Ns 5, 48 of Surah Saba ) (E.N. 45 of YaSeen).

As for the question when it will actually come, the knowledge of it is with Allah, not with me, and there is no need of this knowledge for administering the warning. This can be better understood by an example. As to the exact time when a person will die, it is only known to Allah; however, all know that everyone has to die one day. Our this knowledge is enough that we may warn a heedless friend of ours that he should look after himself and his interests before death. For this warning it is not necessary to know the exact day on which he will die.
