The Kalimat Tayyib.

[Abu Hafsat]

As-Salaam alaikum, 

Just take a moment and consider it, the earth cannot contain 'LA ILAHA ILLALLAH'.. Everything in creation disappears in it. 

So, say it, recite it! All secrets that Allah Ta'ala created will enter it and all the Divine Attributes are in it, and that is why Allah likes us to say this Beautiful Kalima. He says nothing can contain 'LA ILAHA ILLALLAH' because it comes from Noorullah, and Noor-an-Nabi comes from Noorullah, that is why you follow the Noor. 

The Prophet's Light is from Allah's Light, so the Noor follows the Noor as it cannot be separated, and it will to its origin..
