If a man wants to travel and he isn’t able to stop in the path for the prayer, is it permissible for him to combine between Thuhr and Asr before he travels?
There is no problem that he does that in the situation of necessity and in times of needs, relying upon the narration of Ibn Abbas that the prophet صلى الله عليه و سلم combined between Thuhr and Asr, and Between Maghrib and Isha without (due to) any fear, nor travelling. It was said to Ibn Abbas what did he (صلى الله عليه و سلم) intend with that? He said he intended not to over burden his nation.
Thus if you find a need then there is no problem to combine between Thuhr and Asr whilst being a resident, during rare situations at times of needs.
