Hadith 500
حَدَّثَنَا أَبُو مُصْعَبٍ، حَدَّثَنَا عَبْدُ الْمُهَيْمِنِ بْنُ عَبَّاسِ بْنِ سَهْلِ بْنِ سَعْدٍ السَّاعِدِيُّ، عَنْ أَبِيهِ، عَنْ جَدِّهِ، أَنَّ رَسُولَ اللَّهِ ـ صلى الله عليه وسلم ـ قَالَ " مَضْمِضُوا مِنَ اللَّبَنِ فَإِنَّ لَهُ دَسَمًا " .
'Abdul-Muhaimin bin 'Abbas bin Sahl bin Sa'd As-Sa'di narraed from his father, from his grandfather, that:
The Messenger of Allah said: "Rinse your mouths after drinking milk, for it has some greasiness in it."
