Hadith 8:2373
Abu Bakr narrated to us, he said: Abda narrated to us, from Hisham ibn Urwa, from his father, that Ibn al-Zubayr used to stay in Mecca for years, and he would enter into the state of ihram for Hajj upon the sighting of the crescent of Dhu al-Hijjah.
حدثنا أبو بكر قال حدثنا عبدة عن هشام بن عروة عن أبيه ان بن الزبير كان يقيم بمكة السنين يهل بالحج لهلال ذي الحجة
