Regarding a house as unlucky
Question

There is a person who lived in a house, and he suffered a great deal of sickness and calamities, which made him and his family regard this house as unlucky. Is it permissible for him to move for this reason?.
Praise be to Allah.There may sometimes be some houses or vehicles or wives which are unlucky, and Allah in His wisdom causes, when one is with them, some harm or loss of benefits and the like. In this case there is nothing wrong with selling this house and moving to another house, and perhaps Allah will cause some good to be in the house to which he moves. It was narrated from the Prophet (blessings and peace of Allah be upon him) that he said: “Bad omens are in three: a house, a woman and a horse.” Some vehicles may be unlucky, some wives may be unlucky, and some houses may be unlucky. If a person sees that, he should understand that it is by the decree of Allah and that Allah by His wisdom has decreed that so that the person will move to another place. And Allah knows best.
