Signs of Allah in leaves

Bright green and living leaves growing out of the dry wood of a branch, water reaching the threadlike veins of the leaves at heights of many meters, the leaves not drying out under the burning sun... these are only a few of the numerous subjects about which trees make one think.
All the above discussion proves that there is one Allah SWT who is the creator and sustainer of this universe and the entire things in universe from the microscopic organism to the macroscopic objects of universe prove the existence of Allah and oneness of Allah.
