In the design of RoBat, other characteristics of bats were also considered to utilize the echoes in the best way possible. Bats move their ears to determine the frequency intervals of sound waves, and in this way they easily overcome the obstacles in front of them and find their prey and catch it. RoBat was also equipped with such ultrasonic detectors to have a perfect mechanism like that seen in bats.
In the development of materials to be used in the production of strong impellers in jet engines, the mother-of-pearl’s structure is imitated. 95% of the mother-of-pearl on the inner layer of many shellfish’s shells is chalk, but mother-of-pearl is 3,000 times stronger than chalk thanks to its composite structure. When this structure is examined, it is seen that microscopic tablets, only eight microns (1 micron=10–6 meters) in width and one half of a micron in depth, are arranged as layers.
The word "rajaai" interpreted as "return" in Qur'an translations has meanings of "sending back" or "returning." As is known, the atmosphere surrounding the Earth consists of many layers. Each layer serves an important purpose for the benefit of life on Earth. Research has revealed that these layers have the function of turning the materials or rays they are exposed to back into space or back down to the Earth. Now let us examine, employing a few fitting examples, this "returning" function of the layers encircling the Earth.
The weight of clouds can reach quite astonishing proportions. For example, a cumulonimbus cloud, commonly known as the thunder cloud, can contain up to 300,000 tons of water. The fact that a mass of 300,000 tons of water can remain aloft is truly amazing. Attention is drawn to the weight of clouds in other verses of the Qur'an

He left them nothing, absolutely nothing! They are poor though very chaste and self-dignified. She refuses to accept any sort of assistance from anyone. And, what I have just done was the only way I could have ever thought of as an indirect way to give her a hand.
In this series of lectures, Dr. Zakir Naik gives an objective analysis of the Muslim belief regarding the Divine origin of the Qur'an, in the light of established scientific discoveries.
At that very moment, I was taught a lesson that I have never forgotten since then. Later on, I called this lesson, “THE GARBAGE TRUCK RULING”. The driver said: “Many people act as a garbage truck. They move around with a load of trash, different types of problems, depression, failure, anger, and disappointment. When the load becomes unbearable or exceeds the limit within their souls
Because of their perception and opinions, both the teacher and the student were unjustly persecuted, tortured, and humiliated in public by the local authorities then, and they were imprisoned in a single cell, while other disciples were kept separate in the central prison of Damascus, still known to-date as al-Qal’ah. Among the imprisoned scholars, there also was a young man named Ibn Kathir who later on became as the most renowned Muslim scholar and compiler of the most comprehensive Qur’anic commentaries ‘Tafsir Ibn Kathir.’
The first female martyr of Islam was a black slave in pre-Islamic Arabia. As we explore her story, one can’t help but wonder: What attracted her to Islam? How did she gather the indomitable courage to defy the norm and embrace change?
So, if someone says something that you may get wrong, hasten to ask him about what he meant to say and to make himself clear on the issue at hand.
