Surah Al-An'am (The Cattle), Verse 90

اُولٰٓىِٕكَ الَّذِیْنَ هَدَی اللّٰهُ فَبِهُدٰىهُمُ اقْتَدِهْ قُلْ لَّاۤ اَسْـَٔلُكُمْ عَلَیْهِ اَجْرًا اِنْ هُوَ اِلَّا ذِكْرٰی لِلْعٰلَمِیْنَ 

Ulaaa'ikal lazeena hadal laahu fabihudaahumuq tadih; qul laaa as'alukum 'alaihi ajran in huwa illaa zikraa lil 'aalameen

“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."”
