Sayyiduna Abu Hurairah (may Allah be pleased with him) narrates: Once some Abyssinians were displaying their war weapons with skill. During this, Sayyiduna Umar (may Allah be pleased with him) arrived and threw pebbles at them. So the Noble Prophet (peace and blessings of Allah be upon him) said: O Umar, let them do it.
