the best place ive ever visted is faisal masjid in pakistan, which was beautiful place mashallah, with the mountains behind it.
the second best place ive ever visted is a place in lahore....where you can see the beloved prophets (may allah send peace and blessings upon him) walking stick and other objects that belonged to him. i think it was called Baad shahai??
