Benefits and Issues:
A building remains standing only as long as its components remain joined together; if the connection and relationship between them end, the building collapses to the ground. In the same way, Muslims should unite and become like a strong wall whose bricks are interlocked and joined together, leaving no gaps between them. Otherwise, they will not remain strong and powerful, just as today, due to their differences and divisions, Muslims possess no standing or status. In every field, they are being humiliated and disgraced, and in fact, they are deprived of both religion and worldly success.
