If this habit is practiced as a means of satisfying Jinn (creatures created from fire) and avoiding calamities and unpleasant incidents, as it appears from what was mentioned that the slaughtering takes place before entering the house and specifically on the threshold, it will be regarded not only as an unlawful habit but also as Shirk (associating others with Allah in His Divinity or worship).If the slaughtering is done to entertain new neighbors, get acquainted with them, thank Allah for the grace of having a new house, show hospitality to relatives and friends on this occasion and inform them about the new house; it is a good thing and the person who does it is praised. Nevertheless, this is usually done when the owners of the house have already started living there and
slaughtering is not specifically done at the threshold or the entrance.May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
