Surah Al-Maeda Verse 43 - English Translation by Mir Aneesuddin
Surah Al-Maedaوَكَيۡفَ يُحَكِّمُونَكَ وَعِندَهُمُ ٱلتَّوۡرَىٰةُ فِيهَا حُكۡمُ ٱللَّهِ ثُمَّ يَتَوَلَّوۡنَ مِنۢ بَعۡدِ ذَٰلِكَۚ وَمَآ أُوْلَـٰٓئِكَ بِٱلۡمُؤۡمِنِينَ
And how do they make you a judge when they have the Torah with them, in which is the judgment of God? Then they will turn back even after that (i.e. after your judgment), and they are not with the believers
