The word of Tawheed (i.e., Laa ilaaha ill-Allah – there is no god but Allah), is the greatest word in existence. For it all of creation was created, the Messengers were sent, and the Books were revealed. It is the word of piety, the foundation of the faith and the pillar of belief, and it is the trustworthy handhold which, whoever grasps it will be saved, and whoever dies believing in it will be blessed with a blessing after which he will never be wretched.
