﴿ بَلِ ٱتَّبَعَ ٱلَّذِينَ ظَلَمُوٓا۟ أَهْوَآءَهُم بِغَيْرِ عِلْمٍۢ ۖ فَمَن يَهْدِى مَنْ أَضَلَّ ٱللَّهُ ۖ وَمَا لَهُم مِّن نَّٰصِرِينَ ﴾

“But nay - they who are bent on evildoing fol­low but their own desires, without having any knowl­edge (of the truth). And who could guide those whom God has [thus] let go astray, and who (thereupon) have none to succour them?”

(Nay, but those who do wrong) those who disbelieved: the Jews and Christians and idolaters (follow their own lusts) i.e. that which they presently follow: Judaism, Christianity and idolatry (without knowledge) or proof. (Who is able to guide him) to Allah's religion (whom Allah hath sent astray) from His religion? (For such) for the Jews, Christians and idolaters (there are no helpers) no one to save them from Allah's chastisement.
