عَنْ رِبْعِيِّ بْنِ حِرَاشٍ عَنْ بَعْضِ أَصْحَابِ رَسُولِ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ قَالَ: أَصْبَحَ النَّاسُ لِتَمَامِ ثَلَاثِينَ يَوْمًا، فَجَاءَ أَعْرَابِيَّانِ فَشَهِدَا أَنَّهُمَا أَهَلَّاهُ بِالْأَمْسِ عَشِيَّةً، فَأَمَرَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ النَّاسَ أَنْ يُفْطِرُوا
It is narrated from a companion that on the thirtieth day of Ramadan, people began the morning in a state of fasting. Meanwhile, two Bedouins arrived and testified that they had seen the moon the previous evening. On this basis, the Messenger of Allah, peace and blessings be upon him, ordered the people to break their fast at that very moment.
