be valid; for all of that is sheer uncertainty (gharar), and nothing subject to such risk may lawfully be the object of an exchange contract.
Section
The two contestants may compete with several arrows that they own jointly, with separate sets for each of them, or even with a single arrow: one of them may discharge his entire round and then the other shoots with the same arrow, or they may alternate—this one shoots once and then that one—because the intended purpose is thereby fulfilled.
Some of al-Shafiʿi’s companions (1) have forbidden a contest fought with a single arrow on condition that each of the two shoots it once.
No sound basis for this prohibition is apparent. Were they to compete with several arrows (2) on the understanding that one archer shoots an arrow and then the other shoots an arrow, it would be valid—just as it is permissible for each of them to complete all of his shots (3) in uninterrupted succession (4) and thereafter let the other begin his turn. They may likewise equalize by allotting two arrows apiece or three arrows apiece (5), for the aim is that they be on equal footing and that equity be maintained between them.
