I`tikaf I`tikaf refers to the religious practice of spending the last ten days of Ramadan (either wholly or partly) in a mosque so as to devote oneself exclusively to worship. In this state one may go out of the mosque only for the absolutely necessary requirements of life, but one must stay away from gratifying one`s sexual desire. The minimum period for i`tikaf is twenty-four hours. I`tikaf is not valid if one is not keeping the fast or if it is done outside the month of Ramadan.
