آداب الأكل والشرب
Ibn ‘Abbās (may Allah be pleased with him) reported that the Prophet (may Allah's peace and blessings be upon him) said: "Do not drink in a single gulp like a camel; rather, drink in two or three (gulps). Mention the name of Allah upon drinking, and praise Him after drinking."
عن ابن عباس -رضي الله عنهما- قال: قال رسول الله -صلى الله عليه وسلم-: «لا تَشْرَبُوا وَاحِدًا كَشُرْبِ البَعِيرِ، ولكن اشْرَبُوا مَثْنَى وثُلاثَ، وسَمُّوا إذا أنتم شَرِبْتُمْ، واحْمَدُوا إذا أنتم رَفَعْتُمْ».
شرح الحديث :
Do not drink in one breath the way a camel drinks; rather, take your breath once or twice while drinking. Say "in the name of Allah" when you drink, and praise Allah after you finish in two or three times.
