Holy Quran says:
"In the creation of the heavens and the earth, and in the alternation of night and day, there are indeed signs for men of understanding"
Well Holy Quran does talk about the desert some of it imagery describes the desert but it also talk about sea, stars, life and mountains. The Quran is the last revealed word of Allah and the basic source of Islamic teachings and laws. The Quran deals with the basis of creeds, morality, and history of humanity, worship, knowledge, wisdom, God-man relationship, and human relationship in all aspects. Comprehensive teaching on which, can be built sound systems of social justice, economics, politics, legislation, jurisprudence, law and international relations, are important contents of the Quran. Hadith, sayings and actions of Prophet Mohammed (PBUH), meticulously reported and collected by his devoted companions. Explained and elaborated the Quranic verses.
The interesting attitude that exists in Quran repeatedly deals with its advice to the reader. The Quran informs the reader about different facts and then gives them advice. Quran is the miracles of Prophecies, Language, Style and Scientific Revelations.The Holy Qur'an is not only a Miracle. It is a Miracle Performer. It brought out the Miracle of transforming an extremely ignorant and backward society into the guardians of knowledge and learning.
If you want to know more about this or that or if you doubt what is said then you should ask those who have knowledge. This is a surprising attitude. It is not usual to have a book that comes from some one without training in geography, biology etc who discuss this subject and then advise the reader to ask men of knowledge if he doubts anything. Yet in every age there has been Muslims who have followed the advice of the Quran and made surprising discovery. If one looks the work of Muslim scientists of many centuries ago, one will find them full of quotations from the Quran. Their work stated that they had done research in such places, looking for some thing.
