Human freedom is realised in the adoption of humanity as an end in itself, for the one thing that no-one can be compelled to do by another is to adopt a particular end. - 'Metaphysical Principles of Virtue
We are following Allah's word. We believe that humanity's only duty is to honor Allah and his prophet Muhammad, peace be upon him. We are implementing what is written in the Koran. If we manage to do so, then of course it will be a success.
The sole meaning of life is to serve humanity by contributing to the establishment of the kingdom of God, which can only be done by the recognition and profession of the truth by every man.
Act in such a way that you treat humanity, whether in your own person or in the person of any other, never merely as a means to an end, but always at the same time as an end.
