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."
