When one mentions Allah's name upon entering his house and upon eating, the devil says (to his companions): 'There is no night shelter nor supper here for you

عَنْ جَابِرِ بْنِ عَبْدِ اللهِ رضي الله عنهما أَنَّهُ سَمِعَ النَّبِيَّ صَلَّى اللهُ عَلَيْهِ وَسَلَّمَ يَقُولُ: «إِذَا دَخَلَ الرَّجُلُ بَيْتَهُ، فَذَكَرَ اللهَ عِنْدَ دُخُولِهِ وَعِنْدَ طَعَامِهِ، قَالَ الشَّيْطَانُ: لَا مَبِيتَ لَكُمْ، وَلَا عَشَاءَ، وَإِذَا دَخَلَ، فَلَمْ يَذْكُرِ اللهَ عِنْدَ دُخُولِهِ، قَالَ الشَّيْطَانُ: أَدْرَكْتُمُ الْمَبِيتَ، وَإِذَا لَمْ يَذْكُرِ اللهَ عِنْدَ طَعَامِهِ، قَالَ: أَدْرَكْتُمُ الْمَبِيتَ وَالْعَشَاءَ».

Jābir ibn ‘Abdullah (may Allah be pleased with him and his father) reported that he heard the Prophet (may Allah's peace and blessings be upon him) say: "When one mentions Allah's name upon entering his house and upon eating, the devil says (to his companions): 'There is no night shelter nor supper here for you.' However, when one does not mention Allah's name upon entering his house, the devil says: 'You have found yourselves a night shelter.' If one does not mention Allah's name when starting to eat, the devil says: 'You have found yourselves both a night shelter and supper.'"
