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 .
It was narrated from Muhammad bin Sad that his father said: "The Messenger of Allah said: "The month is like this and like this and like this,"' meaning twenty-nine. Yahya bin Saeed and others narrated it from Ismail, from Muhammad bin Sad, from the Prophet.
