Saba' - 34:47

قُلْ مَا سَأَلْتُكُم مِّنْ أَجْرٍ فَهُوَ لَكُمْ إِنْ أَجْرِيَ إِلَّا عَلَى اللَّهِ وَهُوَ عَلَى كُلِّ شَيْءٍ شَهِيدٌ
[34:47]
Say: Whatever reward I have asked of you, that is only for yourselves; my reward is only with Allah, and He is a witness of all things.
Say: "No reward do I ask of you: it is (all) in your interest: my reward is only due from Allah: And He is witness to all things."
Say: Whatever reward I might have asked of you is yours. My reward is the affair of Allah only. He is Witness over all things.
