It is narrated from Hazrat Ibn Abbas (may Allah be pleased with them both) that Hazrat Duba’ah bint Zubair bin Abdul Muttalib came to the service of the Noble Prophet (peace and blessings be upon him) and said,“O Messenger of Allah (peace and blessings be upon him)! I intend to perform Hajj, so should I set a condition for it?”The Prophet (peace and blessings be upon him) said,“Yes, set a condition.”She asked,“What should I say?”The Prophet (peace and blessings be upon him) said,“Say: Labbayk Allahumma Labbayk, and enter into Ihram from the place where you are prevented.”
