In the Sultanate period, the term "fawazil" referred to the excess amount paid to the exchequer by the iqtadars.

During the Sultanate period, the iqtadars were appointed as provincial governors and were responsible for collecting revenue from their assigned territories. The revenue collected by the iqtadars was divided into two parts - the "mal" (official revenue) and the "fawazil" (excess revenue). The "mal" was the fixed amount that the iqtadars were required to remit to the central treasury as their share of revenue. However, if the iqtadar collected more revenue than the fixed amount, the excess amount was referred to as "fawazil."

The "fawazil" was considered additional revenue beyond the iqtadar`s assigned quota, and it was expected to be remitted to the central treasury. However, in practice, some iqtadars would keep the excess revenue for their personal use or for other purposes, instead of remitting it to the treasury. This practice of retaining the excess revenue by the iqtadars was known as "fawazil."

Therefore, in the Sultanate period, "fawazil" meant the excess amount paid to the exchequer by the iqtadars.
