He then set out until, when he reached the rear side of al-Baida', he said: There is one command both for Hajj and Umra. so bear witness. Ibn Rumh said: I call you as witness that I have undertaken to perform my Hajjalong with my Umra (i. e.

He then proceeded pronouncing Talbiya for both of them together until he reached Mecca, He circumambulated the House. and (ran) between al-Safa' and al-Marwa and made no addition to it. He neither sacrificed the animal, nor got his head shaved, nor got his hair clipped, nor did he make anything lawful which was unlawful (due to Ihram) until it was the Day of Sacrifice (10th of Dhu'l-Hijja). He then offered sacrifice, and got his hair cut, and saw that circumambulation of Hajj and 'Umra was complete with the first circumambulation. Ibn 'Umar said: This is how Allah's Messenger (ﷺ) had done
