Musannaf Ibn Abi Shaybah 28831 — The penetrating body wound: how much

It is narrated from Sa'id bin al-Musayyib that some people were shooting arrows, and a man among them shot an arrow that missed its mark and struck a man's belly, passing through to his back and coming out. He was then treated and recovered. The matter reached Sayyiduna Abu Bakr (may Allah be pleased with him), and he gave the judgment of blood money (diyah) equal to two internal wounds.
