When one is emptying his bowels and/or bladder, if the front or back of his body faces qibla and he turns his private parts away from qibla, it will not suffice. Furthermore, the obligatory precaution is that when one is emptying his bowels and/or bladder, he must not sit in a way that his private parts face qibla, nor must he sit in a way that his private parts face in the direction that is directly opposite qibla.
