Arabic (Original)
حَدَّثَنَا سُلَيْمَانُ بْنُ حَيَّانَ عَنِ الْحَسَنِ يَعْنِي ابْنَ عُبَيْدِ اللَّهِ عَنْ سَعْدِ بْنِ عُبَيْدَةَ سَمِعَ ابْنُ عُمَرَ رَجُلًا يَقُولُ اللَّيْلَةَ النِّصْفُ فَقَالَ وَمَا يُدْرِيكَ أَنَّهَا النِّصْفُ بَلْ خَمْسَ عَشْرَةَ سَمِعْتُ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ يَقُولُ الشَّهْرُ هَكَذَا وَهَكَذَا وَهَكَذَا وَضَمَّ أَبُو خَالِدٍ فِي الثَّالِثَةِ خَمْسِينَ.
English Translation
Sulayman ibn Hayyan told us, from al-Hasan - that is, Ibn Ubaydullah - from Sa'd ibn Ubayda: Ibn Umar heard a man say, "Tonight is the middle [of the month]," so he said: "How do you know it is the middle? Rather it is the fifteenth. I heard the Messenger of Allah, peace and blessings be upon him, say: 'The month is like this, and like this, and like this'" - and Abu Khalid closed [his fingers] on the third time.
