Changing one's mazhab
Q:
1. Is it permissible to change and switch between mazhabs more then once? For example, for one to say he's a Hanafi but then decides to become a Shaafi and then become a Hanafi again.
2. Is it permissible for one to adopt a different mazhab because of need. For example, for a Shaafi to become a Hanafi while they are performing tawaaf so if any female has to touch them by mistake their wudhu won't break?
