"The Messenger of Allah milked a sheep and drank some of its milk, then he called for water and rinsed his mouth and said: 'It has some greasiness in it.'" (Using translation from Ibn Mājah 501)
أَنَّهُ قَالَ شَرِبَ رَسُولُ اللهِ ﷺ لَبَنًا ثُمَّ دَعَا بِمَاءٍ فَمَضْمَضَ ثُمَّ قَالَ إِنَّ لَهُ دَسَمًا
