32- 351 – On the authority of Abu Musa al-Ashaari in a narration ascribed to the Prophet:
‘Every Muslim has to give Sadaqa (charity).’ It was asked what if it cannot be found? He said: ‘He should work with his hands, so he benefits himself and gives Sadaqa.’ It was asked: ‘What if that cannot be done?’ He said: ‘He helps the person who is in need and is troubled.’ It was asked: ‘What if that cannot be done?’ He said: ‘Command good actions or goodness.’ It was asked: ‘What if he does not do that?’ He said: ‘Keeping away from evil is indeed Sadaqa.’
