Re: Masjid-Al-Haraam (Makkah) in Future
^ Br / Sr. :
A person never learns if they don't ask. So questions such as yours would not be considered dumb.
The word Haraam as in Masjid-ul-Haraam is from the root word *ha ra ma spelled as huruma or harama *which means 'sacred' or 'having sanctity'.
So Haraam means the 'boundaries of Sanctity' and in religious context it means that 'which is outside the sacred boundaries of deen'.
Simillarly Muharram-ul-Haraam ~ the very sacred month which has sacred limits assigned with it.
I hope this clarifies things for you.
