A Person is called a Mufrid who performs Hajj without umrah. This type of Hajj is called Hajj E Ifrad.
Enter into Ihram with niyah for Hajj only. Ifraad means entering ihraam for Hajj only. When the pilgrim reaches Makkah he performs tawaaf al-qudoom (tawaaf of arrival) and saa’i for Hajj, but he does not shave or cut his hair and does not exit ihraam, rather he remains in ihraam until he exits ihraam after stoning Jamarat al-‘Aqabah on the day of Eid. If he delays the saa’i of Hajj until after the tawaaf of Hajj, there is nothing wrong with that.
There are three types of Hajj: Tamattu’, Ifraad and Qiraan.
Hajj Tamattu Consist of the Following:
Tamattu’ means entering ihraam for ‘Umrah only during the months of Hajj (the months of Hajj are Shawwaal, Dhu’l-Qi’dah and Dhu’l-Hijjah; see al-Sharh al-Mumti’, 7/62). When the pilgrim reaches Makkah he performs tawaaf and saa’i for ‘Umrah, and shaves his head or cuts his hair, and exits ihraam. Then when the day of al-Tarwiyah, which is the 8th of Dhu’l-Hijjah, comes, he enters ihraam for Hajj only, and does all the actions of Hajj. So Tamattu’ involves a complete ‘Umrah and a complete Hajj.
The actions done in Qiraan are the same as those done in Ifraad, except that the pilgrim doing Qiraan has to offer a hadiy (sacrifice) whereas the pilgrim doing Ifraad does not.
The best of these three types of Hajj is Tamattu’. This is what the Prophet (peace and blessings of Allaah be upon him) enjoined upon his companions and urged them to do. Even if a person enters ihraam for Qiraan or Ifraad, then it is strongly recommended for him to change his intention to ‘Umrah, then complete ‘Umrah and exit ihraam, so that he will then be doing Tamattu’. He may do that after doing tawaaf al-qudoom and saa’i – because when the Prophet (peace and blessings of Allaah be upon him) did tawaaf and saa’i during his Farewell Pilgrimage, and his companions were with him, he told everyone who did not have a sacrificial animal (hadiy) to change his intention and make his ihraam for ‘Umrah and to cut his hair and exit ihraam, and he said, “Were it not that I have brought the hadiy with me, I would do what I have commanded you to do.” Sahih Muslim 1211
