The Holy Quran 23:72 — Surah Al-Mu'minun
Arabic text
أَمْ تَسْـَٔلُهُمْ خَرْجًا فَخَرَاجُ رَبِّكَ خَيْرٌ ۖ وَهُوَ خَيْرُ ٱلرَّٰزِقِينَ
Translation
Or is it that (they refuse to accept because) you (O Rasulullaah ﷺ) ask repayment from them (and they find it difficult to pay you)? (This reason if assumed to be true is foolish because) The payment of your Rabb is best and He is the Best of Providers (why then would anyone prefer their payment to Allaah's?).
Tafsir (excerpt) — Tafsir Usmani
The call of the Prophet ﷺ is selfless: that is, in calling them, conveying the message, admonishing and wishing them well, you do not seek any recompense from them. The wealth of both worlds which Almighty Allah has granted you is far better than such recompense.
