Riyad as-Salihin 729
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] .
وعن جابر، رضى الله عنه قال‏:‏ سمعت رسول الله صلى الله عليه وسلم يقول‏:‏ ‏
"‏إذا دخل الرجل بيته، فذكر الله تعالى عند دخوله وعند طعامه، قال الشيطان لأصحابه‏:‏ لا مبيت لكم ولا عشاء، وإذا دخل ، فلم يذكر الله تعالى عند دخوله، قال الشيطان‏:‏ أدركتم المبيت؛ وإذا لم يذكر الله تعالى عند طعامه قال‏:‏ أدركتم المبيت والعشاء‏"‏ ‏. ((رواه مسلم))
