Jabir heard the Prophet (peace be upon him) say: A Muslim is he from whose hand and tongue the Muslims are safe. (Muslim 14)

Narrated AbuHurayrah: Allah’s Messenger (peace be upon him) said: A Muslim is one from whose tongue and hand the Muslims are safe and a believer is one in whom people place their trust in regard to their life and wealth. (Al-Tirmidhi 3)

Narrated Abdullah bin Amr: The Prophet (peace be upon him) said, “A Muslim is the one who avoids harming Muslims with his tongue and hands. And a Muhajir (emigrant) is the one who gives up (abandons) all what Allah has forbidden.” (Al-Bukhari 1:9)
