A'isha (Allah be pleased with her) reported that Allah's Apostle ﷺ went (to the house of) Duba'a bint al-Zubair b. Abd al-Muttalib. She said: Messenger of Allah, I intend to perform Hajj, but I am ill. Thereupon Allah's Apostle ﷺ said: Enter Into the state of Ihram on condition that you would abandon it when Allah would detain you.

وَحَدَّثَنَا عَبْدُ بْنُ حُمَيْدٍ، أَخْبَرَنَا عَبْدُ الرَّزَّاقِ، أَخْبَرَنَا مَعْمَرٌ، عَنِ الزُّهْرِيِّ، عَنْ عُرْوَةَ، عَنْ عَائِشَةَ، - رضى الله عنها - قَالَتْ دَخَلَ النَّبِيُّ ﷺ عَلَى ضُبَاعَةَ بِنْتِ الزُّبَيْرِ بْنِ عَبْدِ الْمُطَّلِبِ فَقَالَتْ يَا رَسُولَ اللَّهِ إِنِّي أُرِيدُ الْحَجَّ وَأَنَا شَاكِيَةٌ . فَقَالَ النَّبِيُّ ﷺ " حُجِّي وَاشْتَرِطِي أَنَّ مَحِلِّي حَيْثُ حَبَسْتَنِي " .
