سنن النسائي

It was narrated from Abu Dharr that the Prophet (ﷺ) said: "There are three at whom Allah will not look on the Day of Resurrection, nor 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 Izar (below the ankles), and the one who sells his product by means of false oaths." (Sahih )
