﴿ وَلَئِن سَأَلْتَهُم مَّنْ خَلَقَ ٱلسَّمَٰوَٰتِ وَٱلْأَرْضَ لَيَقُولُنَّ ٱللَّهُ ۚ قُلْ أَفَرَءَيْتُم مَّا تَدْعُونَ مِن دُونِ ٱللَّهِ إِنْ أَرَادَنِىَ ٱللَّهُ بِضُرٍّ هَلْ هُنَّ كَٰشِفَٰتُ ضُرِّهِۦٓ أَوْ أَرَادَنِى بِرَحْمَةٍ هَلْ هُنَّ مُمْسِكَٰتُ رَحْمَتِهِۦ ۚ قُلْ حَسْبِىَ ٱللَّهُ ۖ عَلَيْهِ يَتَوَكَّلُ ٱلْمُتَوَكِّلُونَ ﴾

“And thus it is [with most people]: if thou ask them, “Who is it that has created the heavens and the earth?” - they will surely answer, “God.” Say: “Have you, then, ever considered what it is that you invoke instead of God? If God wills that harm should befall me, could those [imaginary powers] remove the harm inflicted by Him? Or, if He wills that grace should alight on me, could they withhold His grace [from me]?” Say: “God is enough for me! In Him [alone] place their trust all who have trust [in His existence].””

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.
