قُلْ هَلُمَّ شُهَدَاءَكُمُ الَّذِينَ يَشْهَدُونَ أَنَّ اللَّهَ حَرَّمَ هَٰذَا ۖ فَإِن شَهِدُوا فَلَا تَشْهَدْ مَعَهُمْ ۚ وَلَا تَتَّبِعْ أَهْوَاءَ الَّذِينَ كَذَّبُوا بِآيَاتِنَا وَالَّذِينَ لَا يُؤْمِنُونَ بِالْآخِرَةِ وَهُم بِرَبِّهِمْ يَعْدِلُونَ (150)
(6:150) Say to them: 'Call your witnesses to testify that Allah forbade such-and-such.' Then if they do testify, neither testify with them *126 nor follow the desires of those who have given the lie to Our signs and who do not believe in the Hereafter and set up equals with their Lord.
*126). A person who is conscious that he should testify only to that which he knows, can never testify that the taboos regarding food and other customs prevalent in their society had been enjoined by God. But if some people are brazen enough to feel no compunction in bearing false witness, then at least the believers should not become their partners in lying. The real purpose in asking them to testify honestly whether their customs and practices had in fact been sanctioned by God, is to stimulate those with some sense of honesty to reflect on the character of their customs and practices. Perhaps when they realize that there is no evidence of those prohibitions having been prescribed by God, some of them may decide to get rid of them.
