The Prophet ﷺ said, "When nightfalls, then keep your children close to you, for the devil spread out then. An hour later you can let them free; and close the gates of your house (at night), and mention Allah's Name thereupon, and cover your utensils, and mention Allah's Name thereupon, (and if you don't have something to cover your utensil) you may put across it something (e.g. a piece of wood etc.).  

عَنِ النَّبِيِّ ﷺ قَالَ إِذَا اسْتَجْنَحَ {اللَّيْلُ} أَوْ كَانَ جُنْحُ اللَّيْلِ فَكُفُّوا صِبْيَانَكُمْ فَإِنَّ الشَّيَاطِينَ تَنْتَشِرُ حِينَئِذٍ فَإِذَا ذَهَبَ سَاعَةٌ مِنَ الْعِشَاءِ فَحُلُّوهُمْ وَأَغْلِقْ بَابَكَ وَاذْكُرِ اسْمَ اللَّهِ وَأَطْفِئْ مِصْبَاحَكَ وَاذْكُرِ اسْمَ اللَّهِ وَأَوْكِ سِقَاءَكَ وَاذْكُرِ اسْمَ اللَّهِ وَخَمِّرْ إِنَاءَكَ وَاذْكُرِ اسْمَ اللَّهِ وَلَوْ تَعْرُضُ عَلَيْهِ شَيْئًا  

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)  

عَنِ النَّبِيِّ ﷺ قَالَ أَغْلِقْ بَابَكَ وَاذْكُرْ اسْمَ اللهِ فَإِنَّ الشَّيْطَانَ لَا يَفْتَحُ بَابًا مُغْلَقًا وَأَطْفِئْ مِصْبَاحَكَ وَاذْكُرْ اسْمَ اللهِ وَخَمِّرْ إِنَاءَكَ وَلَوْ بِعُودٍ تَعْرُضُهُ عَلَيْهِ وَاذْكُرْ اسْمَ اللهِ وَأَوْكِ سِقَاءَكَ وَاذْكُرْ اسْمَ اللهِ  

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»  

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)   

"أغْلِقَ بَابَك، واذكُرْ اسمَ اللهِ، فإِن الشيطان لا يفتحُ بابا مُغْلقًا، وأطفِئْ مِصْبَاحَك، واذكُر اسْمَ اللهِ، وأوك سقاءك، واذكر اسم الله، وخمر إناءك واذكر اسم الله، ولو بعودٍ يُعْرَضُ عَلَيهِ".
