Allah subhanahu wa ta’ala is the Rabbi Al-Alamin, the Lord of all that exists: all the people, certainly, but also all the sentient beings, everything with a soul, and, indeed, everything without a soul. Rocks and trees and stars perform their functions exactly as Allah made them, and as for everything else, well…
Sheikh Dr. Yasir Qadhi puts it better than I could, and what struck me about this particular, brief lecture is that Allah azza wa jall is the Rab (Lord, Soverign, Master) of all that exists, and that He made everything to work together in some form or fashion, and that if anything doesn’t work together, it’s because of us, because we interfered in some way, took things too far, were reckless with our vicegerency.
Think about it. Do plants and animals have to recycle anything? And what do we recycle? All the garbage we make, all the plastics and papers and glass and metal, everything that we make, pretty much. Allah’s creation is already taken care of, on its own. Everything Allah made just works, without flaw or error or waste.
