Sahih Bukhari – Hadith No : 4395

Narrated ‘Ata: Jabir said, “The Prophet ordered `Ali to keep the state of Ihram.” Jabir added, “Ali bin Abi Talib returned (from Yemen) when he was a governor (of Yemen). The Prophet said to him, ‘With what intention have you assumed the state of Ihram?’ `Ali said, “I have assumed Ihram with an intention as that of the Prophet.” Then the Prophet said (to him), ‘Offer a Hadi and keep the state of Ihram in which you are now.’ `Ali slaughtered a Hadi on his behalf.”
