أَخْبَرَنَا سُوَيْدُ بْنُ نَصْرٍ، قَالَ أَنْبَأَنَا عَبْدُ اللَّهِ، عَنْ إِسْمَاعِيلَ، عَنْ مُحَمَّدِ بْنِ سَعْدٍ، عَنْ أَبِيهِ، قَالَ قَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم ‏ "‏ الشَّهْرُ هَكَذَا وَهَكَذَا وَهَكَذَا ‏"‏ ‏.‏ يَعْنِي تِسْعَةً وَعِشْرِينَ ‏.‏ رَوَاهُ يَحْيَى بْنُ سَعِيدٍ وَغَيْرُهُ عَنْ إِسْمَاعِيلَ عَنْ مُحَمَّدِ بْنِ سَعْدٍ عَنِ النَّبِيِّ صلى الله عليه وسلم ‏.‏
