Sahih Muslim 106b

Abu Bakr ibn Khallad al-Bahili narrated to me; Yahya—that is, al-Qattan—narrated to us; Sufyan narrated to us; Sulayman al-A'mash narrated to us, from Sulayman ibn Mushir, from Kharashah ibn al-Hurr, from Abu Dharr, from the Prophet (peace and blessings be upon him), who said: ‘There are three to whom Allah will not speak on the Day of Resurrection: one who gives something only to remind the recipient of his favor, one who sells his goods with a false oath, and one who lets his lower garment hang below his ankles.’
