Sincere Muslims cannot, do not, and will not work against each other. Unity of purpose can only be achieved through knowledge and understanding. A Muslim, no matter where he resides, should promote understanding, discipline and compassion among other Muslims. It is quite obvious that any human being will support an effort if it has an excellent chance of succeeding. We want our efforts to benefit all the oppressed people and we have a guarantee that we will succeed.
Harmony necessitates consultation and cooperation.
Disharmony and disunity in expression cannot be encouraged, condoned or even tolerated in Islam. Urgent steps must be taken when this does occur. We may speak about unity of expression, and also declare our unity of purpose but unity in action is not something that we speak about but which we must demonstrate in our daily lives and particularly in our struggle against oppression, exploitation and injustice. Grievously odious is it in the sight of Allah that ye say that which ye do not. Truly Allah loves those who fight in His Cause in battle array as if they were a solid cemented structure.
