What constitutes a valid hit when the condition is absolute hitting ('hawasil')?

Primary text

When the agreed condition is absolute hitting ('hawasil'), the hit is counted provided the arrow strikes the target with its point (nabl). If the arrow strikes with its side or above the point, such as when the arrow turns over before the target and strikes above where it should, it is not counted because this constitutes a poor error in shooting. Likewise, if an arrow breaks into two pieces and the second piece strikes the target, it is not counted.
