Bismillah.
Volume 3, Book 33, Number 249:
Narrated 'Amra:
Aisha (radiallaahu `anhaa) said, "the Prophet (sallallaahu `alayhi wasallam) used to practice Itikaf in the last ten days of Ramadan and I used to pitch a tent for him, and after offering the morning prayer, he used to enter the tent." Hafsa (radiallaahu `anhaa) asked the permission of 'Aisha (radiallaahu `anhaa) to pitch a tent for her and she allowed her and she pitched her tent. When Zainab bint Jahsh (radiallaahu `anhaa) saw it, she pitched another tent. In the morning the Prophet (sallallaahu `alayhi wasallam) noticed the tents. He said, 'What is this?" He was told of the whole situation. Then the Prophet (sallallaahu `alayhi wasallam) said, "Do you think that they intended to do righteousness by doing this?" He therefore abandoned the Itikaf in that month and practiced Itikaf for ten days in the month of Shawwal."
Volume 3, Book 33, Number 250:
Narrated 'Aisha (radiallaahu `anhaa):
The Prophet (sallallaahu `alayhi wasallam) intended to practice Itikaf and when he reached the place where he intended to perform Itikaf, he saw some tents, the tents of 'Aisha (radiallaahu `anhaa), Hafsa (radiallaahu `anhaa) and Zainab (radiallaahu `anhaa). 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.
Prophet (sallallaahu `alayhi wasallam) feared that the wives' intentions might be inclined more towards pleasing him rather than pleasing Allah, so he abandoned I`tikaaf to discourage such behavior. Aren't wives (Mothers of the Believers, and wives in general) so cute? :)
