Hadith 8:7
Abu Bakr narrated to us, he said: Muhammad ibn Fudayl narrated to us, from ‘Ata’ ibn al-Sa’ib, from Mujahid, who said: While ‘Umar was sitting by the House (the Ka’bah), some men from Iraq arrived as pilgrims. They performed the circumambulation (tawaf) of the House and performed the circumambulation between al-Safa and al-Marwah. ‘Umar called them and said: "Did you perform Hajj for other than Him (Allah)?" They said: "No." He said: "Did you remain (in the state of Ihram)?" They said: "Yes." He said: "Did you perform the Umrah?" They said: "Yes." He said: "If that is the case, then restart the work (the rituals)."
حدثنا أبو بكر قال حدثنا محمد بن فضيل عن عطاء بن السائب عن مجاهد قال بينما عمر جالسا عند البيت إذ قدم رجال من العراق حجاجا فطافوا بالبيت وطافوا بين الصفا والمروة فدعاهم عمر فقال أنهزكم لله غيره فقالوا لا فقال أبقيتم قالوا نعم فقال ادهر ثم قالوا نعم قال أما لا فاستأنفوا العمل
