Is zakat obligatory on the principal amount of Islamic Sukuk bonds that is reclaimed after their maturity, given that zakat was annually paid on their returns?

The Zakat on Islamic Sukuk depends on the type of asset invested:

1. If the asset is in trade goods (e.g., real estate for sale): The value of the principal and the profits are subject to Zakat upon the completion of the hawl (lunar year), and the initial hawl is maintained when the sukuk are sold or the cash is redeemed. 2. If the asset is in income-generating assets not intended for trading (e.g., real estate or vehicles for rent): Only the profits are subject to Zakat. When the sukuk are sold or the price is redeemed, a new hawl begins for this cash from the date of its possession.

The difference between the two cases lies in the continuation or recommencement of the hawl, as trade goods do not cease their hawl by being converted into cash.
