What is the importance of drinking water in sitting position?.
Praise be to Allaah. It is permissible to drink both sitting and standing, although drinking whilst sitting is better, and it is what the Prophet (blessings and peace of Allah be upon him) did most often. This has been discussed in the answer to question number 21147. Ibn al-Qayyim (may Allah have mercy on him) said, explaining the negative effect of drinking whilst standing and the importance of drinking whilst sitting: Drinking whilst standing has numerous negative effects, one of which is that it does not fully quench the thirst and does not settle in the stomach so that the liver can distribute the nutrients to other parts of the body. Rather it comes to the stomach with speed and force, and there is the fear that it will cause a chill or disturbance, and may pass quickly to the lower parts of the body without moving gradually. All of that is harmful to the drinker, but if he does it occasionally or in the case of need, it will not harm him… End quote from Zaad al-Ma‘aad, 4/229.
