I am travelling to Iraq for 10 days during the month of Rajab,
I will be staying in Najaf for 4-5 days and same for Karbala. Is it okay for me to fast the day I am in one city or am I not allowed to?
Also is it okay if we want to offer our prayer with the jamaat or offering qasr prayer is obligatory?

1- You cannot fast. It would not be valid to fast.

2- Yes you can pray Jama’a even if you are praying Qasr.
