(8) باب قَبُولِ شَهَادَةِ الرَّجُلِ الْوَاحِدِ عَلَى هِلاَلِ شَهْرِ رَمَضَانَ وَذِكْرِ الاِخْتِلاَفِ فِيهِ عَلَى سُفْيَانَ فِي حَدِيثِ سِمَاكٍ
It was narrated that Ibn 'Abbas said:
"A Bedouin come to the Prophet and said; 'I have sighted the crescent tonight.' He said: 'Do you bear witness that there is none worthy of worship except Allah, and that Messenger?' He said: 'Yes.' He said: 'O Bilal, announce to the people that they should fast tomorrow. "'
