وَمَا تَسْأَلُهُمْ عَلَيْهِ مِنْ أَجْرٍ إِنْ هُوَ إِلاَّ ذِكْرٌ لِّلْعَالَمِينَ
[12:104]
And you do not ask them for a reward for this; it is nothing but a reminder for all mankind.
And no reward dost thou ask of them for this: it is no less than a message for all creatures.
Thou askest them no fee for it. It is naught else than a reminder unto the peoples.
