Yusuf • EN-AL-JALALAYN
﴿ وَمَا تَسْـَٔلُهُمْ عَلَيْهِ مِنْ أَجْرٍ ۚ إِنْ هُوَ إِلَّا ذِكْرٌۭ لِّلْعَٰلَمِينَ ﴾
“although thou dost not ask of them any reward for it: it is but [God's] reminder unto all mankind.”
Nor do you ask them any wage that you should take for it that is for the Qur’ān — it namely the Qur’ān is but a reminder an admonition to all the worlds.
