Joining salaahs when travelling
Q: Is it permissible to join the salaahs when a person undertakes a journey and is a musafir?
Example, you are leaving a country and it is zuhr time so before the flight you join Zuhr and asr? Or you visited a country and you go to a shop and maghrib time sets in so you read maghrib and Isha together? Is this permissible and if not, does one get a sin when they do it?
