حَدَّثَنَا آدَمُ، حَدَّثَنَا شُعْبَةُ، حَدَّثَنَا جَبَلَةُ بْنُ سُحَيْمٍ، سَمِعْتُ ابْنَ عُمَرَ، يَقُولُ قَالَ النَّبِيُّ صلى الله عليه وسلم " الشَّهْرُ هَكَذَا وَهَكَذَا وَهَكَذَا ". يَعْنِي ثَلاَثِينَ، ثُمَّ قَالَ " وَهَكَذَا وَهَكَذَا وَهَكَذَا ". يَعْنِي تِسْعًا وَعِشْرِينَ يَقُولُ، مَرَّةً ثَلاَثِينَ وَمَرَّةً تِسْعًا وَعِشْرِينَ.
