NASAI-KUBRA 3732:
from Ṭāwus And ʿIkrimah Yukhbirān —
'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)." (Using translation from Nasāʾī 2767)
الكبرى للنسائي ٣٧٣٢:
عن طاوس و عكرمه يخبران —
عَنِ ابْنِ عَبَّاسٍ جَاءَتْ ضُبَاعَةُ بِنْتُ الزُّبَيْرِ إِلَى رَسُولِ اللهِ ﷺ فَقَالَتْ يَا رَسُولَ اللهِ إِنِّي امْرَأَةٌ ثَقِيلَةٌ وَإِنِّي أُرِيدُ الْحَجَّ فَكَيْفَ تَأْمُرُنِي أَنْ أُهِلَّ؟ قَالَ «أَهِلِّي وَاشْتَرِطِي إِنَّ مَحِلِّي حَيْثُ حَبَسْتَنِي»
