Surah Al-Mu'minun, ayah 72

أَمۡ تَسۡـَٔلُهُمۡ خَرۡجٗا فَخَرَاجُ رَبِّكَ خَيۡرٞۖ وَهُوَ خَيۡرُ ٱلرَّٰزِقِينَ ٧٢

Am tas'aluhum kharjan fakharāju rabbika khayrun wahuwa khayrur-rāziqīn

Or do you, [O Muḥammad], ask them for payment? But the reward of your Lord is best, and He is the best of providers.
