setting

Ibn'Umar (Allah be pleased with-both of them) reported Allah's Messenger (ﷺ) as saying

The month of Ramadan may consist of twenty-nine days. So do not fast till you have sighted it (the new moon) and do not break fast, till you have sighted it (the new moon of Shawwal), and if the sky is cloudy for you, then calculate.
