Do not attach yourself to any particular creed exclusively, so that you may disbelieve all the rest; otherwise you will lose much good, nay, you will fail to recognize the real truth of the matter. God, the omnipresent and omnipotent, is not limited by any one creed, for he says, 'Wheresoever ye turn, there is the face of Allah' (Koran 2:115). Everyone praises what he believes; his god is his own creature, and in praising it he praises himself. Consequently, he blames the disbelief of others, which he would not do if he were just, but his dislike is based on ignorance.
'Ibn Arabi: Heir to the Prophets'
By William C. Chittick
The importance of Muhyi al-Din Ibn al-Arabi (1165-1240) for Islamic mysticism lies in the fact that he was a speculative thinker of the highest order, albeit diffuse and difficult to understand. His central doctrine is the unity of all existence. In this text, William Chittick explores how, through the work of Ibn Al-Arabi, Sufism moves away from anguished and ascetic searchings of the heart and conscience and becomes a matter of speculative philsophy and theosophy.
