﴿ وَلَوْ كَانُوا۟ يُؤْمِنُونَ بِٱللَّهِ وَٱلنَّبِىِّ وَمَآ أُنزِلَ إِلَيْهِ مَا ٱتَّخَذُوهُمْ أَوْلِيَآءَ وَلَٰكِنَّ كَثِيرًۭا مِّنْهُمْ فَٰسِقُونَ ﴾

“For, if they [truly] believed in God and their Prophet and all that was bestowed upon him from on high, they would not take those [deniers of the truth] for their allies: but most of them are iniquitous.”

(If they) i.e. the hypocrites (believed in Allah) genuinely believed in Allah (and the Prophet) Muhammad (and that which is revealed unto him) i.e. the Qur'an, (they would not choose them) i.e. the Jews (for their friends) seeking their assistance and help. (But many of them) from among the people of the Book (are of evil conduct) they are hypocrites. It is also said that this means: if the Jews genuinely believed in Allah, and in Allah's divine Oneness, and believed in the Prophet (pbuh) and that which was revealed to him, i.e. the Qur'an, they would not have taken Abu Sufyan and his followers for friends, seeking their assistance and help. Nonetheless, many among the people of the Book are disbelievers.
