If a woman had a little amount of coloured discharge on 17/07/12 and then only clear discharge until 19/07/12 when the period starts properly then which date does one take as the beginning of haidh?
If the duration from the 17/07/12 from the time of seeing the coloured discharge till the end of her bleeding is 10 days or less, then her Haidh will have started from the time of the coloured discharge on the 17/07/12.
However if it is more than ten days, then however many days her Haidh was in the previous month will be considered Haidh and the rest will be Istihaadhah. Therefore, she will have to repeat the prayers she missed during the Istihaadah period.
In both cases the period will be counted from the 17th. Wallahu A’lam
