Musnad Ahmad 1153:1282

'Abd al-Razzaq narrated to us, Ma'mar informed us, from al-Zuhri, from 'Urwah, from 'Aishah, who said: "The Prophet, peace and blessings of Allah be upon him, did not test the believing women except by the verse which Allah, the Mighty and Majestic, said: {When the believing women come to you pledging to you that they will not associate anything with Allah} [al-Mumtahanah: 12], and nothing else."
