Nor is it hidden how weak is the line of argument Imām al-Ḥaramayn forced upon al-Shāfiʿī’s words: there is, in fact, no analogy that conflicts with the common practice whereby one archer shoots first. Thus, even had the parties expressly stipulated that a particular competitor begin, the stipulation would not run counter to analogy; and if the custom itself is for one of them to start, that likewise does not contradict analogy. God knows best.

Section on the Shooting Position and Disputes Concerning It
When the archers form ranks opposite the target and each shoots from the spot where he is standing, the contest is valid by unanimous agreement of jurists and marksmen. They are not obliged to take turns occupying the position directly in line with the target. If they all agree to do so, it is permissible; but should they compete for that coveted spot—each wanting to stand squarely before the target just as they vie for the right to shoot first—two opinions have been recorded: (1) the matter is settled by drawing lots; (2) precedence is given to the person designated by the stake-setter, or to whoever enjoys a special claim by virtue of having put up the stake, as noted earlier.
