Is zakat due on a borrowed amount of money that has been held for a full year (hawl) and used to complete the construction of a house, and is zakat due on the building that is still a skeletal structure?

Zakat (definition) is obligatory on wealth that is fully owned, provided a year has passed over it (hawl) and it reaches the

nisab (definition), whether it is intended for building a house or not. If the owner of the wealth is in debt, the

majority of scholars hold that debt can reduce or nullify zakat on inward wealth if the debt

encompasses the wealth or reduces it below the nisab. Accordingly, zakat becomes obligatory if a

year has passed over the borrowed amount and it reaches the nisab after deducting the debt owed

by the owner of the wealth; otherwise, it is not obligatory. As for the building itself, zakat is not

obligatory on it unless it is prepared for trade and sale.
