Quran 7:93 from Surah Al-A'raaf on Divine Marvels.
فَتَوَلَّىٰ عَنۡهُمۡ وَقَالَ يَٰقَوۡمِ لَقَدۡ أَبۡلَغۡتُكُمۡ رِسَٰلَٰتِ رَبِّي وَنَصَحۡتُ لَكُمۡۖ فَكَيۡفَ ءَاسَىٰ عَلَىٰ قَوۡمٖ كَٰفِرِينَ
English translation: So he turned away from them and said O my people! Verily I (have) conveyed to you (the) Messages (of) my Lord and advised [to] you So how could I grieve for a people (who are) disbelievers
Transliteration: fatawalla anhum waqala yaqawmi laqad ablaghtukum risalati rabbi wanasahtu lakum fakayfa asa ala qawmin kafirina
