Qays bin Abi Hazim (may Allah have mercy on him) said: Umar (may Allah be pleased with him) said to Sayyidah Asma' bint Umays (may Allah be pleased with her): We preceded you in emigration. She said: "Yes, by Allah! You did precede us, but we were among barefoot, unclothed people, while you were with the Messenger of Allah (peace and blessings be upon him), who would teach the ignorant among you, give understanding to the learned among you, and command you to the loftiest morals."
