﴿ وَلَوْ أَنَّهُمْ ءَامَنُوا۟ وَٱتَّقَوْا۟ لَمَثُوبَةٌۭ مِّنْ عِندِ ٱللَّهِ خَيْرٌۭ ۖ لَّوْ كَانُوا۟ يَعْلَمُونَ ﴾

“And had they but believed and been conscious of Him, reward from God would indeed have brought them good-had they but known it!”

(And if they) i.e. the Jews (had believed) in Muhammad and the Qur'an (and kept from evil) repented from Judaism and sorcery, (a recompense from Allah) a reward from Allah (would be better) than Judaism and sorcery, (if they only knew) if they believed in Allah's reward, but they do not know nor do they believe; and it is said that they knew all this from their Book.
