﴿ وَأَنِ ٱحْكُم بَيْنَهُم بِمَآ أَنزَلَ ٱللَّهُ وَلَا تَتَّبِعْ أَهْوَآءَهُمْ وَٱحْذَرْهُمْ أَن يَفْتِنُوكَ عَنۢ بَعْضِ مَآ أَنزَلَ ٱللَّهُ إِلَيْكَ ۖ فَإِن تَوَلَّوْا۟ فَٱعْلَمْ أَنَّمَا يُرِيدُ ٱللَّهُ أَن يُصِيبَهُم بِبَعْضِ ذُنُوبِهِمْ ۗ وَإِنَّ كَثِيرًۭا مِّنَ ٱلنَّاسِ لَفَٰسِقُونَ ﴾

“Hence, judge between the followers of earlier revelation in accordance with what God has bestowed from on high, and do not follow their errant views; and beware of them, lest they tempt thee away from aught that God has bestowed from on high upon thee. And if they turn away [from His commandments], then know that it is but God's will [thus] to afflict them for some of their sins: for, behold, a great many people are iniquitous indeed.”

(So judge between them by that which Allah hath revealed�) [5:49]. Said Ibn �Abbas: �A group of Jews which included Ka�b ibn Asad, �Abd Allah ibn Suriya and Shas ibn Qays said to each other: �Let us go to Muhammad lest we seduce him from his religion�. When they went to him, they said: �O Muhammad, you know that we are the rabbis and nobles of the Jews, and if we were to follow you, the Jews will follow us without objection. We will believe in you and confirm your message in exchange for a favour: we have a dispute with some people and we want you to judge in our favour against them�. The Messenger of Allah, Allah bless him and give him peace, refused to do so, and Allah, exalted is He, revealed about them (� but beware of them lest they seduce thee from some part of that which Allah hath revealed unto thee�)�.
