The two main signs of ALLAH Kareem are His signs in the Universe about the systems going on in it and His signs in the heavenly revealed scriptures both Quran and Hadith.

When one thinks and observe deeply, he/she notices the perfection in the systems and the persistency in them along with the way its carrying on its process and the synchronization between them all which ultimately contributes to an ecosystem, the perfect circle of processes yielding life and much more. Every turn of it and every aspect of it bears witness that its Creator is one who is beyond our imagination and yet very very close to us. It testifies that there is no other than the Creator Himself and He is all in all in every single matter and indeed it(system) will come to its inevitable END.
