Etiquette of Eating :
Umar bin Abu Salamah (May Allah be pleased with him) reported:
The Prophet Mohammed SallAllaho Alaihi Wa Salam, said to me, “Mention Allah’s Name (i.e., say Bismillah before starting eating), eat with your right hand, and eat from what is near you.”
‘Ayesha (May Allah be pleased with her) reported:
Messenger of Allah (Mohammed SallAllaho Alaihi Wa Salam) said, “When any of you wants to eat, he should mention the Name of Allah in the begining, (i.e., say Bismillah). If he forgets to do it in the beginning, he should say Bismillah awwalahu wa akhirahu (I begin with the Name of Allah at the beginning and at the end).”
Jabir (May Allah be pleased with him) reported:
I heard Messenger of Allah (Mohammed SallAllaho Alaihi Wa Salam) saying, “If a person mentions the Name of Allah upon entering his house or eating, Satan says, addressing his followers: ‘You will find no where to spend the night and no dinner.’ But if he enters without mentioning the Name of Allah, Satan says (to his followers); ‘You have found (a place) to spend the night in, and if he does not mention the Name of Allah at the time of eating, Satan says: ‘You have found (a place) to spend the night in as well as food.”‘
Hudhaifah (May Allah be pleased with him) reported:
When we attended a meal with the Messenger of Allah (ﷺ), we would not stretch forth our hands towards the food until he (ﷺ) would start eating first. Once, we were with him when a little girl rushed in as if someone was impelling her. She was about to lay her hand on the food when the Messenger of Allah (ﷺ) caught her hand. Then a bedouin came in rushing as if someone were pushing him. He (ﷺ) caught his hand also and said, “Satan considers that food lawful for himself on which the Name of Allah is not mentioned. He (Satan) brought this girl to make the food lawful through her but I caught her hand. Then he brought the bedouin to make it lawful through him but I caught his hand too. By Him in Whose Hand my soul is, now Satan’s hand is in my grasp along with their hands.” Then he mentioned the Name of Allah and began to eat.
Whenever the Prophet (ﷺ) finished a meal, he would say: “Al-hamdu lillahi hamdan kathiran taiyyiban mubarakan fihi, ghaira makfiyyin wa la muwadda`in, wa la mustaghnan `anhu, Rabbuna.
(All praise is due to Allah, praise which is abundant, pure, and full of blessings, which is indispensable and to which one cannot be indifferent).’
