I have constructed a new house. Please tell me which date & day is suitable to enter new house .

All perfect praise be to Allaah, The Lord of the Worlds. I testify that there is none worthy of worship except Allaah, and that Muhammad is His slave and Messenger.

Religiously, there is no desirable specific date when to enter a new home. Whoever builds a new home may enter it on any day he wishes. Indeed, it is forbidden to be pessimistic about a given date or day.

For more benefit, please refer to Fataawa 85004, 82589, 87521 and 92273.
