إِنَّآ أَنزَلۡنَآ إِلَيۡكَ ٱلۡكِتَٰبَ بِٱلۡحَقِّ لِتَحۡكُمَ بَيۡنَ ٱلنَّاسِ بِمَآ أَرَىٰكَ ٱللَّهُ ۚ وَلَا تَكُن لِّلۡخَآئِنِينَ خَصِيمًا
We have sent down to thee the Book in truth, that thou mightest judge between men, as guided by Allah: so be not (used) as an advocate by those who betray their trust;<br/>
Tu'ma ibn Ubayriq stole a coat of mail and hid it with a Jew. When it was discovered with the latter, Tu'ma accused him of having stolen it, and swore by God that he [Tu'ma] had not stolen it, and his clan asked the Prophet may peace and salutation be upon him to advocate on his behalf and absolve him, whereupon the following was revealed: Surely We have revealed to you the Book, Al-Qur'an, with the truth (bi'l-haqq is semantically connected to anzalnaa, 'We have revealed') so that you may judge between people by that which God has shown you, what God has taught you. And do not be a disputant for traitors, like Tu'ma, disputing on their behalf.
