Sahih Bukhari

[life]

Abu Hurayrah (May Allah be pleased with him) narrated that Prophet Mohammad said:"Do you know what backbiting is?” They said, “Allah {Subhanahu Wa Ta'ala} and His Messenger know best.” He then said, “It is to say something about your brother that he would dislike.” Someone asked him, “But what if what I say is true?” The Messenger of Allah said, “If what you say about him is true, you are backbiting him, but if it is not true then you have slandered him."


Narrated Abu Huraira: The Prophet said, "Whoever does not give up false statements (i.e. telling lies), and evil deeds, and speaking bad words to others, Allah {Subhanahu Wa Ta'ala} is not in need of his (fasting) leaving his food and drink."

Those who reject Allah and hinder (men) from the Path of Allah,- their deeds will Allah render astray (from their mark).
But those who believe and work deeds of righteousness, and believe in the (Revelation) sent down to Muhammad - for it is the Truth from their Lord,- He will remove from them their ills and improve their condition.

Surah Muhammad [47:1-2]
