[Machine] I heard the Messenger of Allah ﷺ saying, "The month is like this and like this and like this," and Abu Khalid included fifty in the third part."  

أحمد:٦٠٧٤حَدَّثَنَا سُلَيْمَانُ بْنُ حَيَّانَ عَنِ الْحَسَنِ يَعْنِي ابْنَ عُبَيْدِ اللهِ عَنْ سَعْدِ بْنِ عُبَيْدَةَ سَمِعَ ابْنُ عُمَرَ رَجُلًا يَقُولُ اللَّيْلَةَ النِّصْفُ فَقَالَ وَمَا يُدْرِيكَ أَنَّهَا النِّصْفُ قُلْ خَمْسَ عَشْرَةَ

سَمِعْتُ رَسُولَ اللهِ ﷺ يَقُولُ الشَّهْرُ هَكَذَا وَهَكَذَا وَهَكَذَا وَضَمَّ أَبُو خَالِدٍ فِي الثَّالِثَةِ خَمْسِينَ
