Riyad Us-Saliheen (Gardens of the Righteous)

Chapter 278
Prohibition of Recounting of Favors

Allah, the Exalted, says:

"O you who believe! Do not render in vain your Sadaqah (charity) by reminders of your generosity or by injury.'' (2:264)

"Those who spend their wealth in the Cause of Allah, and do not follow up their gifts with reminders of their generosity or with injury.'' (2:262)

1588. Abu Dharr (May Allah be pleased with him) said: The Prophet (PBUH) observed: "There are three (types of) people to whom Allah will neither speak on the Day of Resurrection nor look at them nor purify them, and they will have a painful chastisement.'' The Messenger of Allah (PBUH) repeated it three times. Abu Dharr (May Allah be pleased with him) remarked: "They are ruined. Who are they, O Messenger of Allah?'' Upon this, the Messenger of Allah (PBUH) said, "One who lets down his lower garments (below his ankels) out of arrogance, one who boasts of his favours done to another; and who sells his goods by taking a false oath.''
[Muslim].

Commentary:  The Hadith makes it evident that it is forbidden for a man to let his lower-body garment go beyond his ankles out of arrogance. The Hadith also makes it clear that it is forbidden to take a false oath with a view to sell one's goods. Messenger of Allah (PBUH) also said in a Hadith reported by Al-Bukhari:"Taking a false oath) helps one sell one's goods well but takes away Allah's blessings from it.''
