﴿ فَأَصَابَهُمْ سَيِّـَٔاتُ مَا عَمِلُوا۟ وَحَاقَ بِهِم مَّا كَانُوا۟ بِهِۦ يَسْتَهْزِءُونَ ﴾

“for all the evil that they had done fell [back] upon them, and they were overwhelmed by the very thing which they had been wont to deride.”

Initially, arguments are used to explain the discourse about God. If man does not accept the Truth despite these arguments, a time will come when it is brought home to him—individually at the time of death and collectively on Doomsday. If the facts about God are explained to a man rationally and he still ignores them, it is as if he is waiting for God and his angels to manifest themselves at some later stage. Then, of course, he would be compelled to accept the Truth. But accepting it at that time will gain him no credit, whereas if he had accepted it when he had the opportunity, prior to God’s appearance, that would have been to his own great credit.
