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.

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