Musnad Ahmad 1154:9

'Abd al-Samad narrated to us, al-Qasim ibn al-Fadl narrated to us, he said: Muhammad ibn 'Ali said to us: 'Umar ibn 'Abd al-'Aziz wrote to me to copy for him the will of Fatimah. And in her will was the curtain which people claim that she introduced, and that the Messenger of Allah, peace and blessings of Allah be upon him, entered upon her, and when he saw it, he turned back.
