O ye who believe! when it is said unto you, Make room! in assemblies, then make room; Allah will make way for you (hereafter). And when it is said, Come up higher! go up higher; Allah will exalt those who believe among you, and those who have knowledge, to high ranks. Allah is Informed of what ye do.
