(bismillah) (salam) wa RAHMATULLAHI WA BARAKATOH. :D So, I was reading the Risalah and in the Mutahiraat section, there were three different ways of change which can make a najis thing Pak/Tahir, such as najis wood burning and changing into ashes makes it Tahir. So, does a change in state (solid, liquid or gas) also make a thing Tahir? For example, if blood has clotted and become solid, does that make it Tahir? Any help on the question will be appreciated! :D
