Al-Ma'idah' - 5:43

وَكَيْفَ يُحَكِّمُونَكَ وَعِندَهُمُ التَّوْرَاةُ فِيهَا حُكْمُ اللّهِ ثُمَّ يَتَوَلَّوْنَ مِن بَعْدِ ذَلِكَ وَمَا أُوْلَـئِكَ بِالْمُؤْمِنِينَ
[5:43]
And how do they make you a judge and they have the Taurat wherein is Allah's judgment? Yet they turn back after that, and these are not the believers.
But why do they come to thee for decision, when they have (their own) law before them?- therein is the (plain) command of Allah; yet even after that, they would turn away. For they are not (really) People of Faith.
How come they unto thee for judgment when they have the Torah, wherein Allah hath delivered judgment (for them)? Yet even after that they turn away. Such (folk) are not believers.
