Hanafi and Witnesses
Therefore, it is not about consistency rather it is about being compelled. Rules of Islamic law can change dependent on circumstances, so if one has no food but pork and he eats what he needs to survive. It is the same principle here, we can choose the local sighting but when performing Hajj one has no choice. Just like making prostration on the back on the person in front of you is allowable at Hajj but that would not be permitted elsewhere.
