Regardless of the conspiracy theories about what certain agencies did or didn't do, it is an inescapable fact that Usambin Ladin and Al Qaeda had a hand in the 911 deadly incident.
The alleged suspects have not denied their involvement. On the contrary they rejoiced and approved the horrifyinf acts.
Such and autrocious act like of Sept 11 that brought down the twon towers and killed many innocent people has no place in the Holy Quran.
Quran admonishes Muslims not to "create disorder on earth," a fundamental principle that applies to both misdemeanor ( minor breach of peace) and felonies ( that involve unlawful deaths and destrcution of properties.)
This binds, compels and influences all Muslims to adopt a positive and peaceful conduct to ensure a peaceful and stable society on earth.
Abiding by this one single principles Billions of Muslims live a most peaceful living surrendering themsleves to thier Lord and Master, Allah the Creator of all worlds.
