It was narrated from Abu Dharr that the Prophet صلی اللہ علیہ وآلہ وسلم said: “There are three at whom Allah will not look on the Day of Resurrection, or will He sanctify them, and theirs will be a painful torment: the one who does not give anything but he reminds (the recipient of his gift), the one who drags his Izbr (below the ankles), and the one who sells his product by means of false oaths.” (Sahih)
