Nafi' said: I killed two birds with a stone in a ravine. One died, and Abdullah ibn Umar (may Allah be pleased with them both) threw it away. I ran to slaughter the other, but it died before I could slaughter it, and Abdullah ibn Umar (may Allah be pleased with them both) threw that one away as well.
