«هذه عمرة استمتعنا بها فمن لم يكن عنده الهدي فليحل الحل كله فإن العمرة قد دخلت في الحج إلى يوم القيامة»
The Prophet (peace and blessings be upon him) said:
"This is an Umrah by which we have performed tamattu'. So whoever does not have a sacrificial animal (hady) with him, let him come out of ihram completely, for Umrah has entered into Hajj until the Day of Resurrection."
