Ya-Sin - 36:21

اتَّبِعُوا مَن لاَّ يَسْأَلُكُمْ أَجْرًا وَهُم مُّهْتَدُونَ
[36:21]
Follow him who does not ask you for reward, and they are the followers of the right course;
"Obey those who ask no reward of you (for themselves), and who have themselves received Guidance.
Follow those who ask of you no fee, and who are rightly guided.
