Mishkat al-Masabih 1895

Abu Musa al-Ashari said: The Messenger of Allah ﷺ said, ‘Every Muslim owes charity.’ They said, ‘What if he does not have anything?’ He said, ‘Let him work with his hands, benefit himself, and give charity.’ They said, ‘What if he cannot, or does not do so?’ He said, ‘Then let him help someone in need and distress.’ They said, ‘What if he does not do that?’ He said, ‘Then let him enjoin what is good.’ They said, ‘What if he does not do that?’ He said, ‘Then let him refrain from evil, for that is charity for him.’
