121. A number of conditions must be observed for the Tamattu Hajj:
a) The niyyah or the intention when declaring and assuming ihraam at the miqaat, when he should intend to perform the Hajj seeking nearness to Allah Almighty.
b) To perform the Hajj and the Umrah in the months of the Hajj, which are Shawwal, Dhil-Qadah, and Dhil-Hejjah.
c) That the Hajj and the Umrah occur in the same year.
d) Declaring and assuming ihraam of the Hajj not the Umrah from the holy city of Makkah, and it is preferable that this is made in the Grand Mosque Masgid al-Haraam. If, due to any peculiar circumstances, it was not possible to do this from the holy city of Makkah, then he should do it from wherever is possible between Makkah and Arafaat. If, due to an oversight or not being conversant with the ruling, one declared the ihraam from elsewhere, and realised this oversight afterwards, it would be imperative for him to go back to Makkah and renew the ihraam from there. If it was not possible to do so, he must declare ihraam from where he is. However, if one deliberately declares and assumes ihraam from other than Makkah, his ihraam would be void, and it would be imperative for him to go back to Makkah and renew his ihraam from there, for otherwise his Hajj would be null and void.
e) The Umrah and Hajj must be performed as "one-by-one", i.e. one may not hire two people to perform the Umrah and Hajj by proxy, in that one of them performs the Umrah and the other performs the Hajj. Likewise it is not permissible for one individual to volunteer to perform by proxy, the Umrah on behalf of a person, and the Hajj on behalf of another.
