Is Zakat obligatory on the value of half a shop used for work, not for trade, and on a house offered for sale with the intention of living in it, not for trade, knowing that a year has passed since the house was offered for sale?

Firstly: The rental contract for a quarter of the shop's income is invalid due to the unknown rent. It must be annulled, and the equivalent rent (ujrat al-mithl) for the past period must be paid. A known rent should be specified upon renewal.

Secondly: The questioner's share of the shop is not subject to zakat as long as he does not intend it for trade, based on the Prophet's (PBUH) saying: "There is no sadaqah (zakat) on a man's slave or horse."

Thirdly: Zakat is due on the shop's rent if a full year (hawl) passes while it is in the questioner's possession. However, it is not obligatory until it is received and a year passes over it, as its ownership is not stable before that.

Fourthly: Zakat is not obligatory on a house offered for sale until it is sold. Its price is then subject to the passing of a year (hawl). If a year passes while the money is in the questioner's possession, its zakat becomes obligatory.
