Al-Ma'idah 5:43

وَكَيْفَ يُحَكِّمُونَكَ وَعِندَهُمُ ٱلتَّوْرَىٰةُ فِيهَا حُكْمُ ٱللَّهِ ثُمَّ يَتَوَلَّوْنَ مِنۢ بَعْدِ ذَٰلِكَ ۚ وَمَآ أُو۟لَـٰٓئِكَ بِٱلْمُؤْمِنِينَ

Wakayfa yuḥakkimūnaka waʿindahumu l-tawrātu fīhā ḥuk'mu l-lahi thumma yatawallawna min baʿdi dhālika wamā ulāika bil-mu'minīna

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