Drinking manners are no less important. To start in the name of Allah is a must. Use your right hand to drink. Abo Dawood and Tirmizi related that Hafsa (RA) said ‘the Prophet SAWS used his right hand for eating and drinking. He used his left for other things [such as personal hygiene].’
Do not pour your drink down your throat in one gulp. Drink it in three sips. Ibn Abbas reported that the Prophet SAWS said ‘Do not drink like a camel. Drink twice or thrice. Say the name of Allah before drinking. Thank Allah after finishing. Do not exhale in your glass. This will irritate others and will smudge the glass or the cup. Ibn Abbas reported that the Prophet SAWS forbade exhaling in a glass or puffing into it. Do not drink directly from the jug or the container. Beside being unhygienic behaviour, others may want to drink after you who could be irritated. Abo Huraira narrated that the Prophet SAWS forbade drinking directly from the mouth of the sheepskin or the flask.
