Is there Zakah due on the land one bought for trade and allowed some orphans to plant it?
If you intend to use this land for business, then it is considered as a commercial commodity and Zakah is due on it. You must calculate the revenues of your land when a Hawl ( one lunar year calculated from the time a property reaches the minimum amount upon which the Zakah is due) passes and is in your possession as the owner, then pay a Zakah of 2.5% of the amount of your calculated revenues if your land has reached its Nisab (the minimum amount on which Zakah is due). If you change your mind and decide to build a house on your land, then no Zakah is due, as it is no longer a commercial commodity in this case.May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
