عَنِ ابْنِ عُمَرَ رَضِيَ اللَّهُ عَنْهُمَا عَنِ النَّبِيِّ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ قَالَ لَا تَشْرَبُوا الْكَرْعَ وَلَكِنْ لِيَشْرَبَ أَحَدُكُمْ فِي كَفَّيْهِ
Sayyiduna Abdullah bin Umar (may Allah be pleased with them both) narrates that the Noble Prophet (peace and blessings be upon him) said: Do not drink water by putting your mouth directly (to the vessel), rather drink water using your hands.
