Women's Issues

Iddah after khula

Q: I have come across a Hadith of Tirmizi which says that the iddah of khula is one menstrual cycle.

But there have been some disputes regarding it and preferable period is three menstrual cycle.
Please clarify this difference of opinion.

If in the case of Khula being one menstrual cycle, can the lady go out and pursue her education if she wants to if after her cycle has ended?

Seeing a pinkish discharge before the days of haidh

Q: A woman spots pinkish discharge 5 days before her period date (she spotted the discharge on the 29th of November and she started bleeding on the 2nd of December) she does sometimes get her periods 3-4 days earlier, her normal habit is 10 days.

So my question is, should she count her Haidh from when she noticed the pinkish discharge or when she actually started bleeding?

Seeing little redness after one's haidh ends

Q: I had haidh for nine days but I thought it was 10 days and I made ghusl because I thought it will be istehaza.. Before performing ghusl I found it clear but immediately after that I found some reddish so I was not sure if it was completely clear or not but before performing ghusl it was clear. In confusion I performed ghusl anyway as I thought it was the 10th day. If I perform salah in this condition is my salah valid. After ghusl I performed asr and maghrib and I never checked during this time. After maghrib I checked and it was clear.. Is my salah valid? Or should I repeat them?
