Tawus and Ikrimah, the freed slave of Sayyiduna Abdullah bin Abbas (may Allah be pleased with them both), narrate from Sayyiduna Abdullah bin Abbas (may Allah be pleased with them both) that Sayyidah Duba'ah bint al-Zubayr bin Abd al-Muttalib (may Allah be pleased with her) came to the Messenger of Allah (peace and blessings be upon him) and said: O Messenger of Allah, I am a heavy woman and I intend to perform Hajj; so how do you instruct me to enter ihram? He (peace and blessings be upon him) said: "Enter ihram and stipulate that my place of leaving ihram will be wherever You hold me back."
