​Guide: Fasting During Ramadan When Ill

(Al-Baqarah: 185) "And whoever is ill or on a journey, (let him break fast, then let him fast) as the days he left on other days. (With the resolution so that) Allah intends for you ease, and He does not put you to difficulties. And also so that you complete the fasting month (Ramadan), and that ye should magnify Allah for having guided you, and that ye may be grateful."
