Sahih Muslim 108 c
The Book of Faith
Clarifying the emphatic prohibition of letting one's garment hang below the ankles (isbal), reminding others of one's gift and selling goods by means of a false oath; Mention of the three to whom Allah, Most High, will not speak on the day of resurrection, nor look at them, nor sanctify them, and theirs will be a painful torment
This hadith has been narrated on the authority of Abu Huraira that he (the Messenger of Allah) observed: Three are the persons with whom Allah would neither speak (on the Day of Resurrection) nor would He look at them, and there would be a painful chastisement for them, a person who took an oath on the goods of a Muslim in the afternoon and then broke it. The rest of the hadith is the same as narrated by A'mash.
