"Duba'ah bint Az-Zubair bin 'Abdul-Muttalib came to the Messenger of Allah and said: 'I am a heavy woman and I want to go for Hajj. How do I begin the Ihram?' He said: 'Enter Ihram and stipulate the condition that you will exit Ihram from the point where you are prevented (from continuing, if some problem should arise)." (Sahih) Ishaq said: I said to 'Abdur-Razzaq: Both from 'Aishah, HIsham and Az-Zuhir? He said: "Yes" Abu 'Abdur-Rahman (An-Nasa'i) said: I do not know of anyone who narrated this chain from Az-Zuhri except Ma'mar.
