It was recorded by Muslim. On the authority of Abu Jamrah, who said: I asked Ibn Abbas about Mut'ah (the enjoyment of performing Umrah during Hajj), and he commanded me to do it. I asked him about the sacrificial offering (hady), and he said: 'It can be a young camel, or a cow, or a sheep, or a share in a blood sacrifice.' Agreed upon. The required blood sacrifice is a sheep, or one-seventh of a cow, or one-seventh of a camel; if one slaughters an entire camel or an entire cow, he has added goodness. This is the opinion of al-Shafi'i and the scholars of opinion (Ashab al-Ra'y).

This is an abandonment of the apparent meaning of the saying of Allah the Almighty: {Then whoever performs Umrah during the Hajj period...}. It is also a disregard for established traditions, and there is no proof in what they argued; for the Prophet's (may Allah bless him and grant him peace) offering of a camel does not negate the sufficiency of what is less than it, for the Prophet (may Allah bless him and grant him peace) drove one hundred camels, and there is no disagreement that this is not obligatory. It is not required that the camel one slaughters be of the same physical description as the camels of the Prophet (may Allah bless him and grant him peace). Furthermore, they maintain that the Prophet (may Allah bless him and grant him peace) was a Mufrid (performing Hajj only) in his pilgrimage. Therefore, they leaned toward preferring Ifrad, so how could his driving of camels be a proof for them regarding Tamattu', when he was not a Mutamatti'!

The second section concerns the conditions that must be met for the blood sacrifice to be obligatory upon the one for whom it is gathered, and these are five: The first is that he enters into ihram for Umrah during the months of Hajj; for if he enters into ihram for it outside of its months, he is not a Mutamatti', regardless of...
