Surah Ali 'Imran · Ayah 110

كُنتُمْ خَيْرَ أُمَّةٍ أُخْرِجَتْ لِلنَّاسِ تَأْمُرُونَ بِٱلْمَعْرُوفِ وَتَنْهَوْنَ عَنِ ٱلْمُنكَرِ وَتُؤْمِنُونَ بِٱللَّهِ ۗ وَلَوْ ءَامَنَ أَهْلُ ٱلْكِتَٰبِ لَكَانَ خَيْرًۭا لَّهُم ۚ مِّنْهُمُ ٱلْمُؤْمِنُونَ وَأَكْثَرُهُمُ ٱلْفَٰسِقُونَ

Kuntum khaira ummatin ukhrijat linnaasi taamuroona bilma'roofi wa tanhawna 'anil munkari wa tu'minoona billaah; wa law aamana Ahlul Kitaabi lakaana khairal lahum minhumul mu'minoona wa aksaruhumul faasiqoon

You are the best nation produced [as an example] for mankind. You enjoin what is right and forbid what is wrong and believe in Allah. If only the People of the Scripture had believed, it would have been better for them. Among them are believers, but most of them are defiantly disobedient.
