Ali 'Imran 110

كُنتُمْ خَيْرَ أُمَّةٍ أُخْرِجَتْ لِلنَّاسِ تَأْمُرُونَ بِٱلْمَعْرُوفِ وَتَنْهَوْنَ عَنِ ٱلْمُنكَرِ وَتُؤْمِنُونَ بِٱللَّهِ ۗ وَلَوْ ءَامَنَ أَهْلُ ٱلْكِتَـٰبِ لَكَانَ خَيْرًا لَّهُم ۚ مِّنْهُمُ ٱلْمُؤْمِنُونَ وَأَكْثَرُهُمُ ٱلْفَـٰسِقُونَ

kuntum khayra ummatin ukh'rijat lilnnāsi tamurūna bil-maʿrūfi watanhawna ʿani l-munkari watu'minūna bil-lahi walaw āmana ahlu l-kitābi lakāna khayran lahum min'humu l-mu'minūna wa-aktharuhumu l-fāsiqūna

You are the best nation produced [as an example] for mankind. You enjoin what is right and forbid what is wrong and believe in Allāh. 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.
