Musnad Ahmad 1119:37

Muhammad ibn Bakr narrated to us, he said: Al-Nahhas informed us, from Shaddad Abu 'Ammar, from 'Awf ibn Malik, he said: The Messenger of Allah (peace and blessings of Allah be upon him) said: "I and a woman with dark-colored cheeks will be like these two on the Day of Resurrection," and he joined his index and middle fingers together. "A woman of status and beauty who became widowed from her husband, and restrained herself for her orphans until they grew independent or died."
