Al-Adab Al-Mufrad #225

Abu Musa reported that the Prophet, may Allah bless him and grant him peace, said, "Every Muslim must give sadaqa." They said, "And if he does not find anything (to give)?" He replied, "Then he should work his hands, benefit himself and then give sadaqa." They asked, "And if he is unable to or does not do it?" He replied, "Then he should help someone with a great need." They said, "And if he does not do it?" He replied, "Then he should command the good or command the correct." They said, "And if he does not do that?" They said, "He should refrain from evil. That is sadaqa for him."
