Lady Aisha (may Allah be pleased with her) narrates that when the Messenger of Allah (peace and blessings be upon him) intended to perform i'tikaf, he would enter the place of i'tikaf after offering the Fajr prayer. On one occasion, he intended to perform i'tikaf during the last ten days of Ramadan, so he ordered a tent to be set up, and it was set up. Lady Aisha (may Allah be pleased with her) also ordered a tent to be set up for her, and it was set up. Lady Hafsa (may Allah be pleased with her) ordered a tent to be set up for her, and it was set up. Lady Zainab (may Allah be pleased with her) saw the tents of both of them, so she ordered a tent to be set up for her as well, and it was set up. When the Messenger of Allah (peace and blessings be upon him) saw this situation, he said: "Are you considering this as righteousness?" Thus, instead of Ramadan, he performed i'tikaf for ten days in Shawwal.
