A rose, for instance, has a strong and constant ever-changing smell. Even with the latest technology, scientists cannot develop an exact match of the smell of the rose. Laboratory research to imitate this smell has not yielded satisfactory results. Smells produced based on the scent of the rose are generally heavy and disturbing. However, the original scent of the rose does not disturb. "It is as Allah wills, there is no strength but in Allah" (Surat al-Kahf: 39).We see trees everyday and everywhere; however, have you ever thought how water reaches the farthest leaf on the top branch of a lofty tree? We can have a better understanding of the extraordinary nature of this by way of a comparison. It is impossible for the water in a tank in the basement of your building to climb to higher floors without a hydrophoric tank or some other powerful engine. You cannot pump water even to the first floor. Therefore, there should also be in trees a pumping system similar to the hydrophoric engine. Otherwise, since water would not be able to reach the trunk of the tree and the branches, trees would soon die.Allah has created each tree with all the necessary equipment. Moreover, the hydraulic system in many trees is too superior to be compared to the building in which one lives.
