Reading Surah Faatiha as a dua during haidh

Q: My wife started an amal quoted in Fazaail-e-Aamal in which she was supposed to recite Surah Faatiha a particular number of times between the sunnat and Farz of Fajr Salaah consecutively for 7 days starting from the first Sunday of the lunar month. After starting the amal for 3 days she started menstruating. What should be done now as her regular menstruating time is around the first Sunday of the lunar month?

Husband telling wife "Let's go to the Qazi and get a talaaq"

Q: One day me and my husband were quarreling. I said that, "you have ruined my life". Hearing that, he became angry and told me two or three times, "ok then, let's go to the Qazi and get a talaq". He did not have any intention to give me talaq or he did not say "talaq talaq talaq or I am giving you divorce". He just told me that to make me feel bad. In this case did the talaq take place?

Musaafir changing his intention

Q: My question is regarding a musaafir:

A person left Verulam with the intention of going to Pietermaritzburg (this is safr distance). On his way, he stops in Chatsworth and changes his mind and says that he is going back home so he reads 4 rakaats asr in Chatsworth as he was told that he is no more a musaafir. Is this correct? When does he become a muqeem and does he have to repeat his asr salaah?
