Is it permissible for someone afflicted with OCD and hemorrhoids, which necessitate performing istinja (washing after using the toilet) and wudu (ablution) for each prayer, to combine prayers while traveling for a week?

We advise the questioner to disregard the obsessive thoughts and not pay attention to them. As for hemorrhoids, they do not necessitate ablution for every prayer unless they are like continuous discharge (sals), in which case it is permissible to combine two prayers according to the Hanbalis. However, if the traveler's stay in the country they are traveling to is four days or more, then they are not permitted to avail themselves of the travel concessions such as shortening and combining prayers. If one combines two prayers due to continuous discharge, then each prayer is complete.
