Battles (Kitab Al-Malahim)
Dawud :: Book 37 : Hadith 4324
Narrated AbuBakr:
You people recite this verse "You who believe, care for yourselves; he who goes astray cannot harm you when you are rightly-guided," and put it in its improper place.
Khalid's version has: We heard the Prophet (peace_be_upon_him) say: When the people see a wrongdoer and do not prevent him, Allah will soon punish them all. Amr ibn Hushaym's version has: I heard the Apostle of Allah (peace_be_upon_him) say: If acts of disobedience are done among any people and do not change them though the are able to do so, Allah will soon punish them all.
