﴿ قُلْ هَلُمَّ شُهَدَآءَكُمُ ٱلَّذِينَ يَشْهَدُونَ أَنَّ ٱللَّهَ حَرَّمَ هَٰذَا ۖ فَإِن شَهِدُوا۟ فَلَا تَشْهَدْ مَعَهُمْ ۚ وَلَا تَتَّبِعْ أَهْوَآءَ ٱلَّذِينَ كَذَّبُوا۟ بِـَٔايَٰتِنَا وَٱلَّذِينَ لَا يُؤْمِنُونَ بِٱلْءَاخِرَةِ وَهُم بِرَبِّهِمْ يَعْدِلُونَ ﴾

“Say: "Bring forward your witnesses who could bear witness that God has forbidden [all] this!" -and if they bear witness [falsely], do not bear witness with them; and do not follow the errant views of those who have given the lie to Our messages, nor of those who believe not in the life to come, and who regard other powers as their Sustainer's equals!”

God has made this world like one great examination hall in which He has left it up to man to do well or badly in the questions of right and wrong. Of course, differentiating between Truth and falsehood should always be based on real reasoning and not on conjecture or on references to popular custom. But man is not bound to opt for the path of logic. For, instead of forcibly imposing His will on man, God adopted the method of teaching man about what is right or what is wrong and left it to him to tread the right or the wrong path. This means that in the life of the world, argument (reasoning) is God’s representative. When a man bows before a correct or sound argument, it is as if he is bowing down before God, and when he refuses to do so, it is as if he is rejecting God. The reason why a man does not accede to reasoning is that he is unable to rise above his desires. In order to justify his actions, he is prepared to declare falsehood to be truth. His recklessness goes to the extent of ignoring God’s signs. He becomes careless of the fact that finally God is going to have him in His grasp, and gives to other things the importance which he should give to God alone.
