What should we do upon moving into a new house for blessings?
You should intend what the pious intended when they moved into a new house. Part of that is to intend that your house be a place of mercy, knowledge, remembrance of Allah and a place in which guests are received and honoured.
It should be a place in which the images of the pious are seen and their voices are heard and not a place where the images of the corrupt are seen and their voices are heard.
You should invite the pious, your relatives and those that you love for Allah’s sake and recite the mawlid along with Surah Ya Sin as a housewarming celebration.
You should recite the Qur’an and the adhkar in the house in abundance. Surat al-Baqarah specifically should be recited , ideally every three days but if that is not possible then at least once.
Whenever any family member enters they should mention Allah’s name and recite Ayat al-Kursi once and Surat al-Ikhlas three times.
