Chapter: Sending 'Ali and Khalid رضي الله عنهما to Yemen
Narrated Ibn `Umar:
The Prophet (ﷺ) assumed the state of Ihram for Umra and Hajj, and we to assumed it for Hajj with him. When we arrived at Mecca, the Prophet (ﷺ) said, "Whoever does not possess a Hadi should regard his Ihram for Umra only." The Prophet (ﷺ) had a Hadi with him. `Ali bin Abi Talib came to us from Yemen with the intention of performing Hajj. The Prophet (ﷺ) said (to him), "With what intention have you assumed the Ihram, for your wife is with us?" `Ali said, "I assumed the lhram with the same intention as that of the Prophet (ﷺ) ." The Prophet (ﷺ) said, "Keep on the state of lhram, as we have got the Hadi."
