Hadith 8:1290
Abu Bakr narrated to us, he said: Muhammad ibn Ja'far narrated to us, from Ash'ath, from al-Hasan, he said: He does not count it. He performs Tawaf around the House, then he performs Sa'i between al-Safa and al-Marwah. If he does not do so until he forgets, he said: He has fulfilled what was upon him, and there is nothing upon him.
حدثنا أبو بكر قال حدثنا محمد بن جعفر عن أشعث عن الحسن قال لا يعتد به يطوف بالبيت ثم يطوف بين الصفا والمروة فإن لم يفعل حتى ينسى قال قد قضى ما عليه ولا شيء عليه
