Al-Ma'idah' - 5:49

وَأَنِ احْكُم بَيْنَهُم بِمَا أَنزَلَ اللّهُ وَلاَ تَتَّبِعْ أَهْوَاءهُمْ وَاحْذَرْهُمْ أَن يَفْتِنُوكَ عَن بَعْضِ مَا أَنزَلَ اللّهُ إِلَيْكَ فَإِن تَوَلَّوْاْ فَاعْلَمْ أَنَّمَا يُرِيدُ اللّهُ أَن يُصِيبَهُم بِبَعْضِ ذُنُوبِهِمْ وَإِنَّ كَثِيراً مِّنَ النَّاسِ لَفَاسِقُونَ
[5:49]
And that you should judge between them by what Allah has revealed, and do not follow their low desires, and be cautious of them, lest they seduce you from part of what Allah has revealed to you; but if they turn back, then know that Allah desires to afflict them on account of some of their faults; and most surely many of the people are transgressors.
And this (He commands): Judge thou between them by what Allah hath revealed, and follow not their vain desires, but beware of them lest they beguile thee from any of that (teaching) which Allah hath sent down to thee. And if they turn away, be assured that for some of their crime it is Allah's purpose to punish them. And truly most men are rebellious.
So judge between them by that which Allah hath revealed, and follow not their desires, but beware of them lest they seduce thee from some part of that which Allah hath revealed unto thee. And if they turn away, then know that Allah's Will is to smite them for some sin of theirs. Lo! many of mankind are evil-livers.
