It is narrated on the authority of Abu Dharr who narrates that the Prophet (may peace be upon him) observed: Three are the persons with whom Allah would not speak on the Day of Resurrection: the bestower of gift who does not give anything but by laying obligation on him, the seller of goods who sells them by taking false oath and one who hangs low his lower garment.
