Volume 3, Book 33, Number 250:
Narrated ‘Aisha:
The Prophet intended to practice Itikaf and when he reached the place where he intended to per –
form Itikaf, he saw some tents, the tents of ‘Aisha, Hafsa and Zainab. So, he said, “Do you consider
that they intended to do righteousness by doing this?” And then he went away and did not perform
Itikaf (in Ramadan) but performed it in the month of Shawwal for ten days.
