عن عمر بن أبى سلمة رضى الله عنهما قال‏:‏ قال لي رسول الله صلى الله عليه وسلم‏:‏‏"‏سم الله وكل بيمينك، وكل مما يليك‏"‏.‏ ((متفق عليه))

Jabir (May Allah be pleased with him) reported

I heard Messenger of Allah (ﷺ) 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."'[Muslim].
