Ghusal after a wet dream

Q: A guy woke up for Fajr prayer. After the Salaah he went back to sleep. He then wakes up later with a "Wet Dream", it happens to be on Sunday, so he decides to take his bath after washing his clothes. Unfortunately he forgot about the Spiritual Bath and does only the normal usual bath. On Wednesday around 8am he remembers that he didn't perform the Spiritual bath but have been praying for the past 3 days and even led some people in prayers during this period. So now what is the ruling on such a person? Does he have to pay for all the prayers he performed during that period? And what about the prayers of the individuals he led, will Allah accept their prayers? What if he had intended to offer the spiritual bath but forgot. Can the bath becomes his ghusal for jannabah?

Talaaq during iddat

Q: My husband gave me divorce on 13 June 2016. It was a talaq-e-bain. Again on 18 august 2016 in anger he gave me oral divorce on the phone saying in the presence of Allah I am giving you talaaq 3 times. My question is whether this talaq is considered as my final talaq or can we both revoke our nikaah? Is it halaal or not?

Mastooraat jamaat

Q: Recently I have noticed that there is an increase in women jamaats (masturaat) coming in our area. Please advise as my wife who attends the weekly taleems has been asked to join the outbound masturaat jamaat with her nephew who is in jamaat being her mahram. Please advise and give your opinion as my personal view is that it is not necessary for females to be out.
