It is narrated from Hazrat Nimran bin Mukhamar Rahbi that he says: Hazrat Abu Ubaidah bin Jarrah was walking with the army and saying: Beware! Many who keep their clothes white make their religion dirty. Beware! Many who honor their own selves actually disgrace them. Beware! Do new good deeds for old evils, because if any one of you fills the space between the earth and the sky with evil, then performs a good deed, this good deed will overcome his evils to the extent that it will bring them down.
