Chapter 10 Virtues of Fasting

Abu Umamah said: ''I {Once} asked, 'O messenger of Allah, tell me to do something'. He said: 'you must fast, for it has no equal {in goodness}'. Then I asked {again}, "O messenger of Allah, tell me to do something something'. He said: 'you must fast, for it has no equal {in goodness}'. I asked {yet again}, 'O messenger of Allah, tell me to do something'. He said: 'you must fast, for it has no equal {in goodness}'''.
Abu Said narrated as follows: ''The prophet said: 'No servant {of Allah} fasts one day for the sake of Allah most high, without Allah distancing his face from Hell-Fire by the measure of seventy autumns {I.e.years' journey}, for the sake of that day'''.
