حَدَّثَنَا مُحَمَّدُ بْنُ جَعْفَرٍ وَبَهْزٌ قَالَا حَدَّثَنَا شُعْبَةُ عَنْ جَبَلَةَ بْنِ سُحَيْمٍ قَالَ بَهْزٌ أَخْبَرَنِي قَالَ سَمِعْتُ ابْنَ عُمَرَ يَقُولُ قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ الشَّهْرُ هَكَذَا وَطَبَّقَ بِأَصَابِعِهِ مَرَّتَيْنِ وَكَسَرَ فِي الثَّالِثَةِ الْإِبْهَامَ قَالَ مُحَمَّدُ بْنُ جَعْفَرٍ فِي حَدِيثِهِ يَعْنِي قَوْلَهُ تِسْعٌ وَعِشْرِينَ
مسند امام احمد بن حنبل · Hadith 5039
Jabalah ibn Suhaym said: I heard Ibn 'Umar say: The Messenger of Allah (PBUH) said: The month is like this," and he clapped his hands twice, then tucked away his thumb on the third time. Muhammad ibn Ja'far said in his hadeeth: meaning: twenty-nine (days).
