19. Abu Ali al-Ash’ari has narrated from Muhammad ibn ‘Abd al-Jabbar from al- Hassan ibn Ali from abu Kahmas from Sulayman ibn Khalid from abu Ja’far who has said the following: “The Messenger of Allah has said, ‘Do you want me to tell you about believers? He is one whose trustworthiness believers trust in matters of their lives and properties. Do you want me to tell you who a Muslim is? He is one from whose tongue and hands Muslims are safe. An immigrant is one who migrates from evils and desists from what Allah has prohibited. It is unlawful for believers to be unjust to a believer, betray him, backbite him or push him aside with a harmful push.’”
