Responding to the question, Sheikh `Abdul-Bari Az-Zamzami, a member of the Moroccan Scholars’ Association, states the following:

There is no contradiction between the content of the verse referred to in the question and the scientific discoveries reached in today’s modern age. The scientists’ discovering the sex of the fetus in the womb, for example, does not mean they have discovered the Unseen; they can learn the fetus’s sex only through using technological methods (such as ultrasound or amniocentesis). During this process, the fetus is “seen”; it is no longer “unseen”. Hence, this has nothing to do with divulging the Unseen.

So is the case with forecasting rain. It depends on meteorological data, such as the direction of wind, clouds, and the other meteorological signs of precipitation. The Prophet (peace and blessings be upon him) said: "If a cloud was formed towards the sea and then seen Levantwards (northwards), know that it would rain heavily." (Reported by Al-Bukhari) According to this hadith, if a rain cloud was formed north of the location of Madinah, this would be a sign that rain would fall on Madinah.

Thus, human knowledge is a result of serious processes of acquiring this knowledge, making a lot of research, and adopting different methods before getting to a certain conclusion in a certain field. But this is not the case with divine knowledge. Allah Almighty is not in need of making research or acquiring knowledge to know about something. He Almighty knows the Unseen without having to use any means to get such knowledge.
