Aslam ualaikum. Let me say that I absolutely love your service, you are a great blessing to the muslim community, May Allah reward you with all the success you so truly deserve. I have some questions, I hope you can help me out with :how far does one have to travel in order to pray the “kasar” or shortened prayers. Also is it must to read the shortened prayer during traveling or can one pray the full normal prayer if he/she wants to. Can they read the sunnahs. And how far or how long can a woman travel without mahram? Under what conditions may one combine Zuhr and Asr or Maghrib and Isha prayers? I had made a vow that I will never miss the 4 sunnahs of Zuhr for a specified time no matter what, if I am in traveling do I have to maintain this vow?
