I am a student in Germany, I recently got a part time internship opportunity in another state. I will be traveling frequently as my university and classes are in one state and my job in another and they are 400-300 km apart. As I will be working part time I will be 3-7 days there and then back to my home for where I am currently living, for the next 6 months. I have a student hostel in both the states. My question is what will be the ruling for my namaz and other faraiz and wajibaat when I will be traveling to the other state for work. Do I have to pray qasr namaz whenever I am in the new city and I would also like to know the rulings on my Fasts in Ramadan.
