Irregular bleeding
Q: A girl got her haidh this morning (Monday 8/8/16 @ abt 11-11.30 am), but her 15 days of cleanliness finished tonight at abt 10-10.30 pm. One mufti's fatwa was that she has to consider the clean-day period between the cycle of last month and the month before (which was 17 days) and only consider herself in the state of haidh once that amount of days are up, even though she's bleeding properly and even after the 15-clean-day-period is up. Another mufti said that once the 15 days are up, she's on her haidh but she has to continue reading salaah until she bleeds for 3 days and more, then she's on her haidh properly and her salaah of those days falls off. Two of her female muallimahs have mentioned that if you bleed after your 15 days you are considered as having haidh and salaah becomes haraam and sinful for you. Please inform me of the fatwa from your perspective. I am not fatwa shopping. I just need clarity on this topic as I myself get confused, which is why I look to you, respected mufti, for clarification. Second question is that she knows she became paak before 10 pm (on Sunday 24/7/16) but hadn't had the chance to make ghusl until that time so after her ghusl she read esha and made qadha of salaah. She's assuming she became paak before esha on Sunday (24/7/17) because the brown/bloody discharge stopped during the course of the day and she found out from 1 of the mentioned muallimahs that haidh had stopped, so she made qadha of those salaah. I know haidh ends soon as bleeding stops, even if one doesn't make ghusl straight away. Now, today she hadn't read esha until 9.45/50 pm & when she went to make wudhu she found blood again even though she hadn't spotted at maghrib time (but she made a fresh wudhu for all salaah) but spotted before and at zohr and asr time. Keeping all of this in mind, will esha qadha of tonight still be binding on her?
