1-Imam Sadiq (AS) quoted the Prophet of Allah (PBUH) saying:
"Whoever builds houses, sacrifices fat sheep, and gives their meat to the poor, and says:
“اللَّهُمَّ اَدْحَرْ عَنّی مَرَدَهَ الجِنِّ وَ الإِنسِ وَ
الشَّیاطینِ، و بارِک لَنا فی بُیوتِنا”
2-The Messenger of God (PBUH) said to Imam Ali (AS):
"O Ali! Whenever you land somewhere,tell this verse (Dua) therefore you May the blessings of that prayer be bestowed on that house, and may its evil be expelled from you.
وَقُل رَّبِّ أَنزِلْنِي مُنزَلًا مُّبَارَكًا وَأَنتَ خَيْرُ الْمُنزِلِينَ
And say: O my Lord! cause me to disembark a blessed alighting, and Thou art the best to cause to alight.(23:29)
3- Another place also it has mentioned that before starting the construction of house one should say 25 times the verse 29 of Sura al-Mumenoon then start his work.
وَقُل رَّبِّ أَنزِلْنِي مُنزَلًا مُّبَارَكًا وَأَنتَ خَيْرُ الْمُنزِلِينَ
And say: O my Lord! cause me to disembark a blessed alighting, and Thou art the best to cause to alight.(Al Mumenoon23:29)
Also you may recite this verse :
[An-Noor:36]:
فِي بُيُوتٍ أَذِنَ اللَّهُ أَن تُرْفَعَ وَيُذْكَرَ فِيهَا اسْمُهُ يُسَبِّحُ لَهُ فِيهَا بِالْغُدُوِّ وَالْآصَالِ
IN THE HOUSES [of worship] which God has allowed to be raised so that His name be remembered in them, there [are such as] extol His limitless glory at morn and evening –
Dua enter the new home:
As cannot count the blessings of Allah (swt) if we think about that, and Allah The Almighty completes the blessing upon us by granting us a new home, and one of the reasons for this blessing is for a person to mention the supplication of the new home and repeat it, and it is desirable for him to repeat some other prayers that has been brought by our beloved Prophet (saww). So should utter the meanings of God’s remembrance of entering and leaving and relying on Him, the Almighty, then He thanks Him, Glory be to Him, for His blessings, and among these supplications:
* بسم الله توكلنا، وبسم الله ولجنا، وبسم الله خرجنا، اللهم نسألك خير المولج وخير المخرج.
* اللهم احفظ بيتنا وبيوت المسلمين جميعا.
* اللهم نسألك البركة والخير والصلاح في منزلنا الجديد.
* اللهم اعطينا خير هذا البيت وقنا شره.
* اللهم بارك لنا في بيتنا هذا وأبعد عنا كل خبيث ومنكر.
* يا رب اجعل هذا البيت سعيد مباركا علينا وارزقنا الأمن والسلام به.
* اللهم بارك لنا فيما رزقتنا وأبعد عنا الحاسدين .
إذ أنه لا حول له ولا قوة في اقتنائه لهذا المنزل وإنما الله تعالى هو من أعطى ووهب، فكلما كان هذا هو شغله الشاغل وتفكيره الدائم، كلما زاده الله نِعمًا فوق النِعم وذلك وفقًا لموعوده سبحانه وتعالى أن يُزيد من يشكره ويُثيبه حيث قال تعالى:« لَئِن شَكَرْتُمْ لَأَزِيدَنَّكُمْ» (إبراهيم، 7).
