  Translation

28. And if you (O Muhammad SAW) turn away from them (kindred, poor, wayfarer, etc. 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).
