65 Preface قُل لا يَعلَمُ مَن فِي السَّماواتِ وَالأَرضِ الغَيبَ إِلَّا اللَّهُ ۚ وَما يَشعُرونَ أَيّانَ يُبعَثونَYusuf AliSay: None in the heavens or on earth, except God, knows what is hidden:1 nor can they perceive when they shall be raised up (for Judgment).The existence of God is certain. But nothing else can be known with certainty to our knowledge. He has told us of the Hereafter, and therefore we know it is true. But those who do not believe in God?what knowledge or certainty can they have? Even when it is actually coming, they will not have the sense to perceive it.
