Ash-Shu'ara' - 26:145

وَمَا أَسْأَلُكُمْ عَلَيْهِ مِنْ أَجْرٍ إِنْ أَجْرِيَ إِلَّا عَلَى رَبِّ الْعَالَمِينَ
[26:145]
And I do not ask you any reward for it; my reward is only with the Lord of the worlds:
"No reward do I ask of you for it: my reward is only from the Lord of the Worlds.
And I ask of you no wage therefor; my wage is the concern only of the Lord of the Worlds.
