First chapter
This is about [the profession of belief]: There is no god but God.
In the Name of God, the Merciful, the Compassionate.
All praise be to the Lord of the Worlds, and peace and blessings be upon the master of the Messengers, his Family, and his Companions.
I bear witness that there is no god but God, Whose necessary Existence and perfect Attributes, and Whose Oneness, Unity, Singularity, and being the Eternally-Besought-of-All are decisively established by the following arguments:
The Prophet as the first proof for God’s Existence and Unity
The first, foremost, and unanimously confirmed truthful witness, and the articulate, verified proof is the lord of the Prophets and Messengers, the leader of all saints and God-conscious scholars. He holds the meaning of the confirmation of God’s Existence and Unity, and the consensus thereon of all Prophets, Messengers, saints, and scholars. He has clear signs [testifying to his Prophethood] and many miracles unanimously confirmed and transmitted by the Companions, later generations, and reliable authorities.
He has lofty, laudable virtues and perfect, admirable morals. He is the center upon which the Divine Revelation is focused, the traveler in the unseen worlds who saw spirits and conversed with angels, and the guide of humanity and jinn. Through his person, he demonstrates that he is the favorite of the Creator of the universe, the embodiment of all perfections shared by creation. The law he brought contains all principles of happiness, which proves that it is the order established by the Orderer of the universe. He is our master who guides us to belief: Muhammad ibn ‘Abdullah ibn ‘Abd al-Muttalib, upon him be the best blessing and most perfect peace.
At the head of all witnesses, he informs us in this visible, material world of what he witnesses in the World of the Unseen. As a bringer of good tidings and a warner, he announces to everyone with his fullest voice and all his strength, perfect earnestness and utmost reliability, and infinite conviction and perfect belief, and regardless of time or place, that there is no god but God.
