How is the zakat calculated for land that was bought and sold in less than a year with the intention of trading, and is the purchase date considered the beginning of a new hawl (zakat year), or does the zakat calculation continue within the original diya (monetary wealth) amount, and what about the zakat on the profits realized during this period?

"Trade capital and its profits follow the principal in the obligation of zakat. You must pay zakat on all the capital you possess upon the completion of a hawl (lunar year) from its acquisition, whether it is intended for trade or not. You should combine the trade profit with the principal and pay zakat on the entirety upon the completion of the hawl for the principal."
