17:28
وَإِمَّا تُعْرِضَنَّ عَنْهُمُ ٱبْتِغَآءَ رَحْمَةٍ مِّن رَّبِّكَ تَرْجُوهَا فَقُل لَّهُمْ قَوْلًا مَّيْسُورًا
wa-immā tuʿ'riḍanna ʿanhumu ib'tighāa raḥmatin min rabbika tarjūhā faqul lahum qawlan maysūran
but if, while seeking some bounty that you expect from your Lord, you turn them down, then at least speak some word of comfort to them.
And if you (O Muhammad صلى الله عليه و سلم) turn away from them (kindred, poor, wayfarer whom We have ordered you to give their rights, but if you have no money at the time they ask you for it) and you are awaiting a mercy from your Lord for which you hope, then, speak unto them a soft kind word (i.e. Allâh will give me and I shall give you).
