Surah Al-Maaida Verse 43

وَكَيْفَ يُحَكِّمُونَكَ وَعِندَهُمُ التَّوْرَاةُ فِيهَا حُكْمُ اللَّهِ ثُمَّ يَتَوَلَّوْنَ مِن بَعْدِ ذَٰلِكَ ۚ وَمَا أُولَٰئِكَ بِالْمُؤْمِنِينَ

Wa kaifa yuhakkimoonaka wa 'indahumut Tawraatu feehaa hukmul laahi summa yatawallawna mim ba'di zaalik; wa maaa ulaaa'ika bilmu'mineen

Translation / The Meaning

But how is it that they come to you for judgement while they have the Torah, in which is the judgement of Allah? Then they turn away, [even] after that; but those are not [in fact] believers.
