Yusuf 12:104
وَمَا تَسْـَٔلُهُمْ عَلَيْهِ مِنْ أَجْرٍ ۚ إِنْ هُوَ إِلَّا ذِكْرٌ لِّلْعَـٰلَمِينَ
Wama tas-aluhum AAalayhi min ajrinin huwa illa thikrun lilAAalameen
And you do not ask of them for it any payment. It is not except a reminder to the worlds.
And you do not demand from them any reward against it. It is nothing but a reminder for all the (people of the) worlds.
