ذِكْرُ الْبَيَانِ بِأَنَّ الْأَمْرَ بِهَذِهِ الْأَشْيَاءِ إِنَّمَا أَمْرٌ مَعَ التَّسْمِيَةِ
Shut your door and make mention of Allah's name, for the devil does not open a door which has been shut; extinguish your lamp and make mention of Allah's name, cover up your vessel even by a piece of wood that you just put on it and make mention of Allah's name, and tie up your water-skin mentioning Allah's name. (Using translation from Abū Dāʾūd 3731)
قَالَ رَسُولُ اللَّهِ ﷺ «أَغْلِقْ بَابَكَ وَاذْكُرِ اسْمَ اللَّهِ فَإِنَّ الشَّيْطَانَ لَا يَفْتَحُ بَابًا مُغْلَقًا وَأَطْفِئْ مِصْبَاحَكَ وَاذْكُرِ اسْمَ اللَّهِ وَأَوْكِ سِقَاءَكَ وَاذْكُرِ اسْمَ اللَّهِ وَخَمِّرْ إِنَاءَكَ وَاذْكُرِ اسْمَ اللَّهِ وَلَوْ بِعُودٍ يُعْرَضُ عَلَيْهِ»
