Ibn al-Arabi gave this advice: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 2:109). 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.
