Abu Muhammad al-Nahdi narrates: Abdullah bin Mas'ud (may Allah be pleased with him) said: "People are of three kinds, and there is no good in anyone besides them: a man who saw a group fighting in the way of Allah and so strove with his life and his wealth; a second man who strove with his tongue, enjoined good and forbade evil; and a third man who recognised the truth with his heart."
