Is Zakat obligatory on money resulting from the sale of a residential house, which will be used to purchase another residential house, knowing that he does not own another house for residence?

Zakat is obligatory on money designated for purchasing a home if a lunar year has passed on it and it has reached the nisab, either by itself or by combining with other funds. However, if a home is purchased with this money before the year has passed, then zakat is not obligatory on it. The fact that a person does not own another house for dwelling does not alter this ruling.
