If you travel from Dubai to Abu Dhabi twice a week for work, do you fast or not? And do you shorten your prayers for the same reason?
Is there a reason behind the waivers God has given us through Coran to not fast when travelling?
Travel gives Muslims licence to shorten prayers and combining them together. As for shortening the prayer, it is probably wajeb (obligatory) while you can choose to combine prayers together or not. Regarding breaking the fast, scholars explain it in details; if there is hardship it is better to break the fast but if there is no hardship it is better to keep fasting.
