Qasar Salaah and Full Salaah

Q: My brother traveled safar distance and when he reached his destination he had no niyyat of how many days he will stay in that place. Will he be a musaafir?

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?

Q: I travelled musaafir distance to one town and had a niyyah to stay for seven days. After seven days I decided to stay another 9 days. Will I be a musafir because my intention was to stay for only 7 days. Now my new intention is 9 days which is less than 15 days.

Q: I go to work by road for 70 km and then by helicopter for 45 min. Sometime I go for seven days (return date is confirmed) and sometimes my return date is not confirmed and depends on the completion of the job. Please tell if I have to pray full prayers?

Q: I returned home from a 7 day holiday in Durban. The time for Asr set in while I was driving. I reached home 45 mins before Magrib and prayed Asr 4 rakaats.

Should I have read Asr as a Musafir or full Salaah? What are the rules regarding Musafir when returning from a journey for a Salaah that has set in but only read when at home?

Q: I want to know if I will read qasr salaah if I don't know how long I will be on holiday for? Most probably it will be for more than 15 days but I'm not sure of the exact date when I will be returning home.

Q: If one is studying in a town that is more than 77kms away from his home town, stays there from Sunday till the following Friday, then returns home on Friday and goes back on Sunday, and continues in this manner throughout the course of the semester, should he perform qasar Salaah or full Salaah?

Q: I live in the university hostel which is 150km away from my home. I go home almost every weekend and return on Monday to the hostel, that means I travel 4 times in a month. So should I pray normal or qasr namaz in the hostel?

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?

Q: How can I calculate 15 days during a journey in order to know whether I need to perform qasar Salaah or full salaah. Suppose I reach a destination on 1st Dec 05:30 pm and plan to stay till 15th Dec 05:30 am.

Do I need to to take into account till 15th Dec 5:30 pm (360 hrs) as it is less than 360 I should offer Qasr even though it is 15th day ?
