Quran 6:90 Al-An'am, ayah 90 of 165

أُو۟لَـٰٓئِكَ ٱلَّذِينَ هَدَى ٱللَّهُ ۖ فَبِهُدَىٰهُمُ ٱقْتَدِهْ ۗ قُل لَّآ أَسْـَٔلُكُمْ عَلَيْهِ أَجْرًا ۖ إِنْ هُوَ إِلَّا ذِكْرَىٰ لِلْعَـٰلَمِينَ ۝٩٠

6:90 Those are they whom Allah guideth, so follow their guidance. Say (O Muhammad, unto mankind): I ask of you no fee for it. Lo! it is naught but a Reminder to (His) creatures.
