Al-An'am - 6:90

أُوْلَـئِكَ الَّذِينَ هَدَى اللّهُ فَبِهُدَاهُمُ اقْتَدِهْ قُل لاَّ أَسْأَلُكُمْ عَلَيْهِ أَجْرًا إِنْ هُوَ إِلاَّ ذِكْرَى لِلْعَالَمِينَ
[6:90]
These are they whom Allah guided, therefore follow their guidance. Say: I do not ask you for any reward for it; it is nothing but a reminder to the nations.
Those were the (prophets) who received Allah's guidance: Copy the guidance they received; Say: "No reward for this do I ask of you: This is no less than a message for the nations."
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.
