502. If a mubtadiÞah—a woman who is observing blood for the first time—observes blood for more than ten days, and all of it possesses the qualities of ÎayÃ, she should consider the habitual duration of her relatives as (the duration of) her ÎayÃ, and the rest as istiÎÁÃah. If she does not have any relatives, or her relatives have varying habits, obligatory precaution dictates that she consider the first three days as ÎayÃ. She should then combine the prohibitions of a ÎÁÞià and the obligations of a mustaÎÁÃah in the first month until the tenth day, and in subsequent months until the sixth or seventh day.
503. If a mubtadiÞah observes blood for more than ten days, some of which possesses the qualities of Îayà and some the qualities of istiÎÁÃah, and the blood with the qualities of Îayà is not discharged for less than three days or more than ten days, then all of it (with the qualities of ÎayÃ) is ÎayÃ.
However, if she observes blood with the qualities of Îayà once again, before ten days have passed after the first discharge with the qualities of Îay×for example, she observes dark blood for five days, followed by yellow blood for nine days, and then dark blood once again for five days—she should consider the middle discharge as istiÎÁÃah. As for the first and third discharge, she should act on precaution by combining the prohibitions of a ÎÁÞià with the obligations of a mustaÎÁÃah.
504. If a mubtadiÞah observes blood for more than ten days, some of which possesses the qualities of Îayà and some the qualities of istiÎÁÃah, but the blood with the qualities of Îayà is discharged for less than three days, then all the observed blood is istiÎÁÃah.
