Question :
                                            
                                            
                                            
                                                Can a Muslim who intended Ihram (Ritual consecration) for any of the three types of Hajj (Ifraad, Tamattue`, Qiraan) change his intention after entering Mecca?
                                            
                                            
                                            The Answer : 
                                            
                                                All perfect praise be to Allah, The Lord of The Worlds, and may His blessings and peace be upon our Prophet Mohammad and upon all his family and companions.                                                                                                                                                                                                                                       
If a Muslim intended Ihram for Umrah during the days of Hajj, he is permitted to combine Hajj with it to perform Qiraan type of Hajj so long as he didn`t offer the arrival circumambulation.                                                                                                                                                                                                 
However, if he intended to perform Ifraad type, then he isn`t permitted to combine it with an Umrah to become Qiraan type of Hajj. And Allah Knows Best.
