Hadith 8:2716
Abu Bakr narrated to us, he said: Ibn Numayr narrated to us, from Abd al-Malik, from a sheikh from the people of Mecca, who said: I saw Ibn Umar performing Tawaf, and the prayer was established, so he entered into the prayer. When he finished the prayer, he resumed his Tawaf.
حدثنا أبو بكر قال نا بن نمير عن عبد الملك عن شيخ من أهل مكة قال رأيت بن عمر يطوف وقد أقيمت الصلاة فدخل في الصلاة فلما قضى الصلاة بنى على طوافه
