In Islamic law, there is no authentic textual evidence from the Qur’an or Sunnah making it obligatory to sacrifice an animal upon purchasing a home. The act of buying a home is a worldly blessing from Allah, and the appropriate response is gratitude (shukr) through permissible means, which can include sadaqah, feeding others, or other forms of charity, but there is no specific sacrifice legislated for this occasion.

Slaughtering a lamb and distributing the meat after buying a house is not obligatory in Islam, nor is it a Sunnah specific to this occasion. It is a permissible cultural practice that can be done as a form of voluntary charity if one wishes, but one may also give sadaqah in other ways. The main requirement is to thank Allah for the blessing, avoid extravagance, and share with others from what He has given.
