All three types are permissible, and the pilgrim has the choice to enter into the state of Ihram and recite the Talbiyah for whichever type of Hajj he wishes: Qiran, Ifrad, or Tamattu’.

Lady Aisha (may Allah be pleased with her) narrates that we set out (for Hajj) near the appearance of the crescent of Dhul-Hijjah. So the Prophet (peace and blessings of Allah be upon him) said: "Whoever wishes to enter into Ihram for only Hajj, let him enter into Ihram for only Hajj (and make the intention for Hajj Ifrad), and whoever wishes to enter into Ihram for only Umrah, let him enter into Ihram for Umrah." Thus, some of us entered into Ihram for Hajj and some entered into Ihram for Umrah.
