Surat Al-Mā'idah - سورة المائدة

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

Muhsin Khan: But how do they come to you for decision while they have the Taurat (Torah), in which is the (plain) Decision of Allah; yet even after that, they turn away. For they are not (really) believers.
