Khāriq li-l-ʿādah means departure from the familiar course of events; it does not mean something logically contradictory or outside divine power. Ordinary events and extraordinary events alike are subject to God's power.
A circumstance being unusual differs from its being logically impossible. The fact that an event is not observed in normal experience does not prove that its occurrence is self-contradictory.
A miracle's probative significance arises through its extraordinary character in the context of a prophetic claim, not through confusion between rarity and contradiction.
