﴿ إِنَّآ أَنزَلْنَا عَلَيْكَ ٱلْكِتَٰبَ لِلنَّاسِ بِٱلْحَقِّ ۖ فَمَنِ ٱهْتَدَىٰ فَلِنَفْسِهِۦ ۖ وَمَن ضَلَّ فَإِنَّمَا يَضِلُّ عَلَيْهَا ۖ وَمَآ أَنتَ عَلَيْهِم بِوَكِيلٍ ﴾

“BEHOLD, from on high have We bestowed upon thee this divine writ, setting forth the truth for [the benefit of all] mankind. And whoever chooses to be guided [thereby], does so for his own good, and whoever chooses to go astray, goes but astray to his own hurt; and thou hast not the power to determine their fate.”

In every age, man has worshipped beings other than God, but nobody has had the courage to say that their deities created the heavens and the earth, or that the real causes of comfort or distress were in their power. It is very strange that, in spite of this uncertainty, people are not ready to leave their false gods. When all the arguments and pleadings of a preacher prove ineffective in influencing his people, the only alternative left for him is to tell them to do whatever they like and to warn them that when the Day of Final Judgement arrives, it will be made clear who is on the right path and who is on the wrong one. This is an expression of certainty on the basis of arguments, and is always the final word of a missionary.
