Sayyiduna Abd al-Rahman bin Awf (may Allah be pleased with him) said: Al-Zubayr bin al-Awwam (may Allah be pleased with him) told me; he said: "On the day of Uhud I saw Hind bint Utbah with her shin uncovered, and it is as if I am looking at the anklets on her shin, while she was urging the people on to fight."
