[Machine] The Messenger of Allah ﷺ said: "Do not begin the month until you see the crescent (of the new moon) or complete the count (of days from the previous month), then fast until you see the crescent (of the new moon) or complete the count (of days). This was narrated by Jarir from Mansur, mentioned by Hudhaifah, who is trustworthy and reliable. It was also narrated by Thawri and a group of narrators from Mansur, from Rib'i, from some of the companions of the Prophet ﷺ, from the Prophet ﷺ."
قَالَ رَسُولُ اللهِ ﷺ لَا تَقَدَّمُوا الشَّهْرَ حَتَّى تَرَوَا الْهِلَالَ أَوْ تُكْمِلُوا الْعِدَّةَ ثُمَّ صُومُوا حَتَّى تَرَوَا الْهِلَالَ أَوْ تُكْمِلُوا الْعِدَّةَ وَصَلَهُ جَرِيرٌ عَنْ مَنْصُورٍ بِذِكْرِ حُذَيْفَةَ فِيهِ وَهُوَ ثِقَةٌ حُجَّةٌ وَرَوَاهُ الثَّوْرِيُّ وَجَمَاعَةٌ عَنْ مَنْصُورٍ عَنْ رِبْعِيٍّ عَنْ بَعْضِ أَصْحَابِ النَّبِيِّ ﷺ عَنِ النَّبِيِّ ﷺ
