باب تَغْلِيظِ تَحْرِيمِ الْجِمَاعِ فِي نَهَارِ رَمَضَانَ عَلَى الصَّائِمِ وَوُجُوبِ الْكَفَّارَةِ الْكُبْرَى فِيهِ وبيانها وأنها تجب على الموسر والمعسر وتثبت في ذمة المعسر حتى يستطيع
Sahih Muslim 1111 b

A hadith like this has been narrated on the authority of Muhammad b. Muslim al-Zuhri with the same chain of transmitters, and he said:

There was brought an 'araq containing dates, an 'araq being a huge basket. But in this hadith no mention has been made of (the fact) that the Messenger of Allah (ﷺ) laughed till his molar teeth became visible.
حَدَّثَنَا إِسْحَاقُ بْنُ إِبْرَاهِيمَ، أَخْبَرَنَا جَرِيرٌ، عَنْ مَنْصُورٍ، عَنْ مُحَمَّدِ بْنِ مُسْلِمٍ الزُّهْرِيِّ، بِهَذَا الإِسْنَادِ ‏.‏ مِثْلَ رِوَايَةِ ابْنِ عُيَيْنَةَ وَقَالَ بِعَرَقٍ فِيهِ تَمْرٌ - وَهُوَ الزِّنْبِيلُ - وَلَمْ يَذْكُرْ فَضَحِكَ النَّبِيُّ صلى الله عليه وسلم حَتَّى بَدَتْ أَنْيَابُهُ ‏.‏
