Fatwa - His Eminence SHAIKH AHMED BIN HAMAD AL KHALILI Grand Mufti of Oman

  Q: If someone broke his fasting on the first day of Ramadhan as he did not know that the crescent has been sighted the day before, is it permissible to fast that day?   A: He should make up for the missed fast day of Ramadhan, without controversy. The Prophet (Peace be upon him) said: “Do not fast until you see the crescent and do not break your fast until you see it.” In fact, one cannot fast unless he observed the crescent of Ramadhan.
