On the last day of my monthly period, I saw some yellowish discharge about two hours before the adhaan of Fajr, then I went to sleep and I did not see whether that discharge stopped before Fajr or not. In the morning I noticed that the discharge had stopped, then I waited for a little while, then the adhaan for Zuhr had been given, and after that I did ghusl. Do I have to make up the prayers that I missed or should I offer Zuhr prayer only? Do I have to make up the fast of that day after Ramadan?.
Praise be to Allaah.
If a woman gets her menses, then the basic principle is that this menses remains until she is certain that it has ended, and it is not permissible for her to fast or pray when she is not sure as to whether her menses has ended or not.
We have discussed that in the answer to question number 106452.
‘Aa’ishah (may Allah be pleased with her) used to tell women to take their time and not to be hasty until they were certain that they had become pure. She used to say: Do not be hasty until you see the white discharge, meaning purity from menses.
Based on that, you do not have to make up Fajr prayer; as for Zuhr prayer you have to offer it because the time for it came when you were pure from menses.
As for the fast, the fast of that day is not valid -- if you fasted it -- because you were menstruating at the beginning of the day, and you have to make it up after the end of Ramadan.
And Allah knows best.
