The Qur'an states that "There is no changing in God's creation." (30:30) According to the Prophet of Islam 'every child is born with an upright nature.' (Al-Bukhari) We learn from this that unity is found among all human beings at the level of nature and creation. Nature forms the common constituent in the creation of human beings, just as the atom forms the common constituent in all the varied objects of nature in the physical world. That is to say that the same unity which exists in the external world at the physical level, has existed among human beings at the spiritual level from the outset.
But man tends at times to be oblivious of his own nature. This is no less true in the sphere of unity. Today people are unaware of their spiritual potential. In such a situation, the easiest way to bring about spiritual unity is to make men aware of that potential. The moment they became aware of it, spiritual unity will come into existence of its own accord.
