LessonsBab al-Sarf: Circulating Fulus, Obsolete Coins and Money-Changer ExchangesQuiz

The final passage completes three interrelated principles:
1. Customary monetary function: circulating and obsolete fulus have different legal treatment.
2. Determinacy by custom: the number of fulus worth half a dirham may be known by established market practice.
3. Allocation of countervalues: expressly assigning halves in a money-changer's deal can change the result compared with requesting an unallocated bundle.
This completes Bab al-Sarf. The next section in Quduri is Kitab al-Rahn, dealing with pledges and security for debts.
