Concise Quran Commentary
If the Jews had really had faith in Allah, and been mindful to obey His sacred law and not rebel, His reward would have been far better for them, if they only knew.
وَلَوْ أَنَّهُمْ ءَامَنُوا۟ وَٱتَّقَوْا۟ لَمَثُوبَةٌ مِّنْ عِندِ ٱللَّهِ خَيْرٌ ۖ لَّوْ كَانُوا۟ يَعْلَمُونَ
If only they had believed and feared Allah, they would have had a better reward from Allah, if only they knew!
