Chapter 16: The Book of Pilgrimage
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.
