Qasar Salaah and Full Salaah

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?

Travelling safar distance

Q: Is it allowed to have 2 watan iqamah at one time?

Does leaving my “watan iqamah”, make my watan iqamah no longer my watan iqamah?

(Does traveling from my watan iqamah make my watan iqamah batil)?

For example - London is my watan iqamah (I’m staying there with intention of 2 years), if I travel to Rome from London, and then I have a flight to Dubai from Rome with a 1 day layover in London. When I’m in London for 1 day, will I pray full or qasr? Basically, when I left my watan iqamah for a few days, will that make my watan iqama null and void? Even if I plan on coming back to it after some time?

Will a person who has two houses in different countries perform full salaah or qasar salaah?

Q: I lived in South africa for many years, then for some reason I moved to another country with my whole family. However, I still have my house in South Africa and I have the intention to come back and live in this house after a few years.

My question is that if I come to my house in South Africa for 3 days just to see if everything is alright, will I be a musaafir or not?
