Surah Al-An'am, ayah 90

6:90

أُوْلَٰٓئِكَ ٱلَّذِينَ هَدَى ٱللَّهُۖ فَبِهُدَىٰهُمُ ٱقۡتَدِهۡۗ قُل لَّآ أَسۡـَٔلُكُمۡ عَلَيۡهِ أَجۡرًاۖ إِنۡ هُوَ إِلَّا ذِكۡرَىٰ لِلۡعَٰلَمِينَ ٩٠

Ulā'ikal-ladhīna hadallāhu fabihudāhumuqtadih qul lā as'alukum 'alayhi ajran in huwa illā dhikrā lil-'ālamīn

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."
