It is narrated from Hazrat Salim (may Allah have mercy on him) that Sayyiduna Ibn Umar (may Allah be pleased with them both) used to cut the socks (below the ankles) of his mahram women, until Hazrat Safiyyah bint Abu Ubaid narrated to him a hadith from Sayyidah Aisha (may Allah be pleased with her) that the Messenger of Allah (peace and blessings be upon him) granted permission for women to wear socks. (So he stopped cutting the socks.)
