Musannaf Ibn Abi Shayba 7:483

Abu Usama narrated to us, he said: Jarir ibn Hazim narrated to us, Ya'la ibn Hakim narrated to me, from al-Zubayr ibn al-Khirrit, from Ikrimah, who said: I did not say anything of these [matters] based on my own opinion. A woman asked me, having vowed to circumambulate the House on four limbs. I said to her: Perform seven circuits for each limb.
