المؤمنون — Al-Mu'minun Ayat 72

اَمْ تَسْـَٔلُهُمْ خَرْجًا فَخَرَاجُ رَبِّكَ خَيْرٌ ۖوَّهُوَ خَيْرُ الرّٰزِقِيْنَ

Am tas'aluhum kharjan fa kharāju rabbika khair(un), wa huwa khairur-rāziqīn(a).

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