﴿ وَكَيْفَ يُحَكِّمُونَكَ وَعِندَهُمُ ٱلتَّوْرَىٰةُ فِيهَا حُكْمُ ٱللَّهِ ثُمَّ يَتَوَلَّوْنَ مِنۢ بَعْدِ ذَٰلِكَ ۚ وَمَآ أُو۟لَٰٓئِكَ بِٱلْمُؤْمِنِينَ ﴾

“But how is it that they ask thee for judgment seeing that they have the Torah, containing God's injunctions - and thereafter turn away [from thy judgment]? Such as these, then, are no [true] believers.”

(How come they unto thee for judgement) regarding stoning, this is mentioned by way of showing amazement (when they have the Torah, wherein) in the Torah (Allah hath delivered judgement (for them)) the judgement of stoning? (Yet even after that) after the exposition in the Qur'an and the Torah (they turn away. Such (folk) are not believers) in the Torah.
