145. The time of the advent of the Last Day is known to God alone Who knows the Unseen which, in fact, is not known even to the Prophet (peace be on him). Being human, he is not aware what the morrow has in store for him and his family. Had his knowledge encompassed everything - even things that lie beyond the ken of sense-perception and events that lie hidden in the future - he would have accumulated immense benefit and would have been able to avoid a great deal of loss owing to such foreknowledge. That being the case, it is sheer naivety to ask the Prophet about the actual time for the advent of the Last Day.
