Sayyiduna al-Zubayr bin al-Awwam (may Allah be pleased with him) narrates the story of Sayyiduna Abu Dujanah, that is, Simak bin Kharashah (may Allah be pleased with him), at Uhud: the Prophet (peace and blessings be upon him) gave him his sword, and whenever he intended to fight, he would mark himself with a headband.
