Fasting of Ramadan Prescribed

In the second year of Hijrah, Allah prescribed fasting the month of Ramadan as an obligation upon the Muslim community through the revelation of Surah al-Baqarah: 'O you who have believed, decreed upon you is fasting as it was decreed upon those before you that you may become righteous' (2:183). The verses also established the Night of Power (Laylat al-Qadr) and the rules of fasting from dawn to sunset. The Prophet fasted nine Ramadans in his lifetime.
