There is absolutely no basis for stipulating a condition that a person should perform a particular ritual such as the sacrifice of a sheep or goat or charity before occupying your new house.

 

However, you may do well to read Surat Al-Baqarah and offer two rak’ahs; if you wish to give some charity or feed the poor that would be optional acts of virtue.

 

A house is either a Devils’ den or tranquil place where angels descend with peace. We have the choice of inviting angels or demons into our homes by our lifestyle.

 

The Prophet (peace be upon him) said, “If a person were to invoke the name of Allah while eating and drinking, and before retiring to bed and upon rising from bed, the devil will say to his troops: he has left you with no food or bed!”

 

So keep the devils out by celebrating the remembrance of Allah and being consistent with it. I pray to Allah to bless your house.

 

Allah Almighty knows best.
