﴿ وَمَآ أَسْـَٔلُكُمْ عَلَيْهِ مِنْ أَجْرٍ ۖ إِنْ أَجْرِىَ إِلَّا عَلَىٰ رَبِّ ٱلْعَٰلَمِينَ ﴾

““And no reward whatever do I ask of you for it: my reward rests with none but the Sustainer of all the worlds.”

(And I ask of you no wage) no payment (therefore) for professing Allah's divine Oneness; (my wage) my reward (is the concern only of the Lord of the Worlds.
