Istihadha

If a woman has a 7-day menstrual period, with the final 2 days being lighter and unsure if it is menstrual bleeding or Istihadha, is it permissible for her to engage in physical intimacy with her husband using a condom? Zaid Alsalami	Is a very small amount of Istihadha considered Najis? If I discover that I had a tiny amount of Istihadha immediately after my prayer, does that render my prayer invalid? Sayyed Mohammad Al-Musawi
What is Istihadha and how can I differentiate it from regular menstruation bleeding? Sayyed Mohammad Al-Musawi	If I missed my last Istihadah prayer before entering Haydh due to being unable to make Ghusl while in university and not at home, should I make up my Istihadah prayers on the same day, or do I make it up after my period ends?<br> Sayyed Mohammad Al-Musawi
