Hazrat Abu Sha’tha’ says that when a pilgrim garlands the sacrificial animal (Hadi), he has entered into the state of Ihram.

Hazrat Ata and Hazrat Aswad say that it is not permissible for a pilgrim that its necklace (of the sacrificial animal) is put on (tied) and he is not in the state of Ihram; however, if he wishes for one or two days, then (there is no harm).

Hazrat Saeed bin Jubair saw a person who had put on (tied) a garland. He said, "When this has been done, then he has become a Muhrim."

Hazrat Ibn Abbas (may Allah be pleased with both of them) says that when the garland was put on the sacrificial animal, then Ihram became obligatory upon it.

Hazrat Ibn Abbas (may Allah be pleased with both of them) says that when the garland is put on (tied) or the animal is marked, then now ihram has become obligatory upon it.

Hazrat Saeed bin Al-Musayyib and Hazrat Sulaiman bin Yasar narrate that Hazrat Saad bin Qais set out with the intention of Hajj or Umrah. When he was at the place of Dhul-Hulaifah, his wife was combing his hair. When his camel was garlanded (its halter was tied), he withdrew his head from the woman's hands and said: Whoever garlands (ties the halter of) this camel, his Ihram is complete.

Hazrat Ata, Hazrat Tawus, and Hazrat Mujahid say that whoever garlanded the Hadi (sacrificial animal) with the intention of Ihram, then he became a Muhrim.

Hazrat Maymun bin Abu Shabib narrates that when the sacrificial animal (Hadi) was garlanded or its side was marked (Ish'ar was done), then the person became a Muhrim (entered the state of Ihram).

A person asked Hasan about the marking of the sacrificial animal for Hadi. He replied: When the Hadi is marked or a collar is put on it during the months of Hajj, then Hajj becomes obligatory upon it. And if a person does this outside the months of Hajj, then Hajj does not become obligatory upon him.

Hazrat Hammad was asked about a person who puts a collar (ties) on his camel? He replied: If he wishes, he does not have to become a Muhrim.
