When a man enters his house and mention Allah’s name on entering and on his food, the devil says: You have no place to spend the night and no evening meal; but when he enters without mentioning Allah’s name on entering, the devil says: You have found a place to spend the night, and when he does not mention Allah’s name at his food, he says: You have found a place to spend the night and an evening meal.
سَمِعَ النَّبِيَّ ﷺ يَقُولُ إِذَا دَخَلَ الرَّجُلُ بَيْتَهُ فَذَكَرَ اللَّهَ عِنْدَ دُخُولِهِ وَعِنْدَ طَعَامِهِ قَالَ الشَّيْطَانُ لاَ مَبِيتَ لَكُمْ وَلاَ عَشَاءَ وَإِذَا دَخَلَ فَلَمْ يَذْكُرِ اللَّهَ عِنْدَ دُخُولِهِ قَالَ الشَّيْطَانُ أَدْرَكْتُمُ الْمَبِيتَ فَإِذَا لَمْ يَذْكُرِ اللَّهَ عِنْدَ طَعَامِهِ قَالَ أَدْرَكْتُمُ الْمَبِيتَ وَالْعَشَاءَ
