It is narrated from Abdur Rahman bin Ajlan (may Allah have mercy on him) that Sayyiduna Umar (may Allah be pleased with him) passed by two men who were shooting arrows. One of them said to the other: "Asbat," meaning "You hit the mark" (although it should be "Asabta"). Sayyiduna Umar (may Allah be pleased with him) said: A mistake in pronunciation is worse than a mistake in archery.
