Allah's Apostle used to practice Itikaf in the middle ten days of Ramadan and once he stayed in Itikaf till the night of the twenty-first and it was the night in the morning of which he used to come out of his Itikaf. The Prophet said, "Whoever was in Itikaf with me should stay in Itikaf for the last ten days, for I was informed (of the date) of the Night (of Qadr) but I have been caused to forget it. (In the dream) I saw myself prostrating in mud and water in the morning of that night. So, look for it in the last ten nights and in the odd ones of them." It rained that night and the roof of the mosque dribbled as it was made of leaf stalks of date-palms.

Hafsa asked the permission of 'Aisha to pitch a tent for her and she allowed her and she pitched her tent. When Zainab bint Jahsh saw it, she pitched another tent. In the morning the Prophet noticed the tents. He said, 'What is this?" He was told of the whole situation. Then the Prophet 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."

And then he went away and did not perform Itikaf (in Ramadan) but performed it in the month of Shawwal for ten days.

Narrated Ali bin Al-Husain:
Safiya, the wife of the Prophet told me that she went to Allah's Apostle to visit him in the mosque while he was in Itikaf in the last ten days of Ramadan. She had a talk with him for a while, then she got up in order to return home. The Prophet accompanied her. When they reached the gate of the mosque, opposite the door of Um-Salama, two Ansari men were passing by and they greeted Allah's Apostle . He told them: Do not run away! And said, "She is (my wife) Safiya bint Huyai." Both of them said, "Subhan Allah, (How dare we think of any evil) O Allah's Apostle!" And they felt it. The Prophet said (to them), "Satan reaches everywhere in the human body as blood reaches in it, (everywhere in one's body). I was afraid lest Satan might insert an evil thought in your minds."
Volume 3, Book 33, Number 252:
Narrated Abu Salama bin 'Abdur-Rahman:
I asked Abu Said Al-Khudri, "Did you hear Allah's Apostle talking about the Night of Qadr?" He replied in the affirmative and said, "Once we were in Itikaf with Allah's Apostle in the middle ten days of (Ramadan) and we came out of it in the morning of the twentieth, and Allah's Apostle- delivered a sermon on the 20th (of Ramadan) and said, 'I was informed (of the date) of the Night of Qadr (in my dream) but had forgotten it. So, look for it in the odd nights of the last ten nights of the month of Ramadan. I saw myself prostrating in mud and water on that night (as a sign of the Night of Qadr). So, whoever had been in Itikaf with Allah's Apostle should return for it.' The people returned to the mosque (for Itikaf). There was no trace of clouds in the sky. But all of a sudden a cloud came and it rained. Then the prayer was established (they stood for the prayer) and Allah's Apostle prostrated in mud and water and I saw mud over the forehead and the nose of the Prophet.

The wives of the Prophet were with him in the mosque (while he was in Itikaf) and then they departed and the Prophet said to Safiya bint Huyai, "Don't hurry up, for I shall accompany you," (and her dwelling was in the house of Usama). The Prophet went out and in the meantime two Ansari men met him and they looked at the Prophet and passed by. The Prophet said to them, "Come here. She is (my wife) Safiya bint Huyai." They replied, "Subhan Allah, (How dare we think of evil) O Allah's Apostle! (we never expect anything bad from you)." The Prophet replied, "Satan circulates in the human being as blood circulates in the body, and I was afraid lest Satan might insert an evil thought in your minds."
