Abstract
In this study we clarified a scientific fact that mentioned in Qur’an as source of irrigation to plants which is the word Tul (which means the dew in Arabic), which mentioned in surat Albagara (265):
The Scientific fact: Recently, many researches provide evidence that dew is a continuous source of water to plants, and some plants depend on dew more than on rain. This is because it is easy for plants to absorb dew from surface of their leaves than waiting for rains to settle down to their roots. The importance of dew motivated many researchers to catch the mist to irrigate food plants in dry regions.
Faces of Scientific fact in Qur’an from the above, we can understand that dew is one of the natural available water resources for plants especially in dry regions. This is because rains has to be heavy enough to go down into the soil and thereafter absorbed by plants.hn the above verse, Allah the Almighty, Has clarified this fact in scientific and precise picture since fourteen century ago. The word which is mentioned in the above verse, means, in Arabic, field of different kinds and shapes of plants .These plants can be with deep roots, medium or shallow roots water from rain available to plant when it settle down into the soil. However, even shallow rooted plants can absorb dew because it is available in their leaves surfaces. This showed the importance of dew to irrigate different kinds of plants. This what was proved recently using many technologies.
Nonetheless, some interpreters suggested that the word means light rains. However this proved not to be true
because light rains will evaporate before plants can benefit from their water, and so no production. The above verse indicated that many fruits come out when these plants absorb the Tul (b).
Dew normally stays on leaves surfaces for many hours, enough for the plants to absorb it. Plants absorb dew through their cuticle or through special cells in their leaves. In some places, the collected dew reached 1.5 inch, which is sufficient for meristematic tissues to grow leading to growth of other parts.
Finally, what Allah the Almighty Has mentioned about the importance of dew a long time ago (longer than basics of plant ecology has been studied), humans discovered it recently.
