Ramadan with the flow, guaranteed everybody fasting
Ramadan (Arabic: رمضان Ramaḍān, IPA: [rɑmɑˈdˤɑːn]; variations Turkish: Ramazān) is the ninth month of the Islamic calendar, which lasts 29 or 30 days. It is the Islamic month of fasting, in which participating Muslims refrain from eating, drinking, smoking and sex  during daylight hours and is intended to teach Muslims about patience, spirituality, humility and submissiveness to God.
