وَكَيْفَ يُحَكِّمُوْنَكَ وَعِنْدَهُمُ التَّوْرٰىةُ فِيْهَا حُكْمُ اللّٰهِ ثُمَّ يَتَوَلَّوْنَ مِنْۢ بَعْدِ ذٰلِكَ ۗوَمَآ اُولٰۤىِٕكَ بِالْمُؤْمِنِيْنَ ࣖ ( المائدة: ٤٣ )
Wa kaifa yuhakkimoonaka wa 'indahumut Tawraatu feehaa hukmul laahi summa yatawallawna mim ba'di zaalik; wa maaa ulaaa'ika bilmu'mineen (al-Māʾidah 5:43)
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. (Al-Ma'idah  : 43)
1 Mufti Taqi Usmani
How do they ask you to judge while the Torah is with them, having the ruling of Allah? Still, they turn away, after all that. They are no believers.
