Is the sacrificial animal obligatory for the one combining Hajj and 'Umrah based on the text?

Question : May Allah bless you. Ibn 'Umar called the Qur'an tamattu' (combining 'Umrah and Hajj with a break between them). Some people have inferred from this that the obligation of the sacrificial animal for the one combining is based on the text, because the phrase "so enjoy your 'Umrah and Hajj" includes the Qur'an and tamattu'. Is that not the standard?

Answer : It has a point, but the expressions of the Companions, or the language of the Companions regarding the description of the Prophet's (peace and blessings be upon him) hadith, vary. He would perform tamattu' and say "pure" or say "I entered the state of ihram." As long as there is a possibility in the matter that this weakens the Companions' certainty or makes them doubt, it does not become a standard in their religion.
