Explaining the Meaning of al-Rabb (Lord) and al-'Alamin (the Worlds)

The Shaykh : Praising Allah (Glorified and Exalted is He), or rather, praising Himself by saying that He is the Lord of the worlds. What is the meaning of "al-Rabb" and what is the meaning of "al-'Alamin"? Al-Rabb is the Owner, the Creator, the Owner, and the Manager. And al-'Alamin is everything other than Allah. Everything other than Allah is a "world," but they are of different types: the world of humans, the world of animals, the world of the celestial bodies, and so on. Everything other than Allah is a world, including the heavens, the earth, the stars, the sun, the moon, and everything else. It is called a "world" because it is a sign of its Creator (Mighty and Majestic); it is a sign of its Creator because everything in the universe is a witness to the signs of Allah.
"And in everything He has a sign *** indicating that He is One"
Therefore, a "world" is everything other than Allah, whether living or non-living, animate or inanimate, because it is a sign of its Creator.
