Tauheed
The oneness of God; the affirmation of strict monotheism.
Literally: making one; affirming oneness
The declaration that God is one and without partner — the bedrock of Islam. Iqbal reads tauheed not merely as a theological proposition but as a living principle of human society: because all power and worship belong to the one God, no human being may be enslaved, deified or set above another. From this he derives equality, freedom and solidarity, arguing that a community truly built on tauheed cannot tolerate caste, race-pride or kingship over conscience.
