What is the ruling on fasting for someone who suffers from chronic migraines that prevent him from completing the fast and cause him to lose consciousness, knowing his difficult financial situation and his inability to feed a needy person?

If illness permits breaking the fast due to severe hardship, the patient must consult doctors. If the illness is expected to be cured, then it is obligatory to make up the days missed as soon as it is possible to do so without hardship. These days remain a debt, and there is no sin in delaying the making up due to inability.
