فَأَنشَأْنَا لَكُمْ بِهِ جَنَّـتٍ مِّن نَّخِيلٍ وَأَعْنَـبٍ لَّكُمْ فِيهَا فَوَكِهُ كَثِيرَةٌ وَمِنْهَا تَأْكُلُونَ - وَشَجَرَةً تَخْرُجُ مِن طُورِ سَيْنَآءَ تَنبُتُ بِالدُّهْنِ وَصِبْغٍ لِّلأَكِلِيِنَ - وَإِنَّ لَكُمْ فِى الاٌّنْعَـمِ لَعِبْرَةً نُّسْقِيكُمْ مِّمَّا فِى بُطُونِهَا وَلَكُمْ فيِهَا مَنَـفِعُ كَثِيرَةٌ وَمِنْهَا تَأْكُلُونَ - وَعَلَيْهَا وَعَلَى الْفُلْكِ تُحْمَلُونَ
18. And We sent down from the sky water in measure, and We gave it lodging in the earth, and verily, We are able to take it away. 19. Then We brought forth for you therewith gardens of date palms and grapes, wherein is much fruit for you, and whereof you eat. 20. And a tree that springs forth from Tur Sinai, that grows oil, and relish for the eaters. 21. And verily, in the cattle there is indeed a lesson for you. We give you to drink of that which is in their bellies. And there are, in them, numerous benefits for you, and of them you eat. 22. And on them, and on ships you are carried. Allah mentions His innumerable blessings to His servants, whereby He sends down rain in due measure, meaning, according to what is needed, not so much that it damages the lands and buildings, and not so little to be insufficient for crops and fruits, but whatever is needed for irrigation, drinking and other benefits. If there is a land that needs a lot of water for its irrigation but its fertile soil would be carried away if rain fell on it, then Allah sends water to it from another land, as in the case of Egypt, which is said to be a barren land. Allah sends the water of the Nile to it, which brings red soil from Ethiopia when it rains there. The water brings the red soil which is used to irrigate the land of Egypt, and whatever of it is deposited is used for agriculture, because the land of Egypt is infertile, and most of it is sand. Glory be to the Subtle One, the All-Knowing, the Most Merciful, the Forgiving.
