وَإِنَّ لَكَ لَأَجْرًا غَيْرَ مَمْنُونٍ (3)
(68:3) and surely yours shall be a never-ending reward, *3
*3) That is, "You will get an unlimited and continuous reward, for although you have to hear discouraging and disturbing things in response to the efforts that you are making for the instruction and guidance of the people, yet you are steadfastly performing your Mission of calling them to the Right Way."
