Surah Al-An'am, Verse 90

أُوْلَٰٓئِكَ ٱلَّذِينَ هَدَى ٱللَّهُۖ فَبِهُدَىٰهُمُ ٱقۡتَدِهۡۗ قُل لَّآ أَسۡـَٔلُكُمۡ عَلَيۡهِ أَجۡرًاۖ إِنۡ هُوَ إِلَّا ذِكۡرَىٰ لِلۡعَٰلَمِينَ٩٠

ulāika alladhīna hadā l-lahu fabihudāhumu iq'tadih qul lā asalukum ʿalayhi ajran in huwa illā dhik'rā lil'ʿālamīna

Those are the ones whom Allāh has guided, so from their guidance take an example. Say, "I ask of you for it [i.e., this message] no payment. It is not but a reminder for the worlds."
