Salim bin Abdullah narrated from his honoured father (Sayyiduna Abdullah bin Umar, may Allah be pleased with them both) that he used to give women the fatwa that they should cut their leather socks, until Safiyyah (may Allah be pleased with her) related to him from Sayyidah Aishah (may Allah be pleased with her) that she gave women the fatwa not to cut them, so he too stopped.
