Hadith.1864 - He said: "I asked him, 'Can a fasting person perform cupping (hijamah)?'
Imam (as) replied: 'I fear for him what he might fear for himself.'
I asked: 'What do you fear for him?'
Imam (as) said: 'Fainting or the stirring of bile.'
I asked: 'What if he is strong enough and does not fear anything?'
Imam (as) said: 'Yes, if he wishes.'"
