Sayyiduna Abu Sa'id Khudri (may Allah be pleased with him) narrates that we observed i'tikaf with the Messenger of Allah (peace and blessings be upon him) during the middle ten days of Ramadan. Then, when the morning of the twentieth night came, we began to move our belongings, so the Prophet (peace and blessings be upon him) ordered us: "Whoever among you has observed i'tikaf should return to his place of i'tikaf, for indeed I was shown this night, then it was made to be forgotten by me, and I was shown that I am prostrating in mud."
