It is by no means logical that a system sent for the bliss and salvation of humanity by Allah - Whose mercy encompasses all creation - be allotted to a handful of people while all others are left devoid of this bounty. This situation contrasts with the Rahman and Raheem attributes of Allah.
The messenger of Allah (blessings and peace be upon him) said:
"God Almighty shows mercy to those who show mercy. Show mercy to those on earth so that those in the Heavens shall show mercy to you." (Abu Dawud, Adab, 58/4941; Tirmizi, Birr 16/1924; Ahmad bin Hanbal, II, 160)
This hadith implies no particular race. Nor does it imply "Muslims-only." It commands us all to be merciful to all human beings, animals, and plants.
Excerpt:
Let us stop and think for a moment. Let us search out where we come from and where we are going. Let us shape our lives accordingly. Before everything, we must think and explore the details about our own creation, our physical and spiritual form, the superior traits that we have, and the universe. Our life becomes more meaningful this way.
As an example, let’s think about the earth. Al-though they are nourished with the same water, thousands of different kinds of plants grow on earth providing fruits and vegetables in different colors and shapes. They do this in perfect form and order. Is it not extraordinary that foods that grow on the same land and are nourished by the same water can be superior to and different from each other?
Let’s turn our eyes to the sky and contemplate this glorious and magnificent system. Take the sun for example. The distance between the sun and the Earth is 150 million kilometers. The sun, one of the intermediate-sized stars, is large enough to contain 1,300,000 Earth-sized planets. Its surface temperature is 6,000°C, the interior temperature is 20,000,000°C. Its orbital velocity is as fast as 720,000 kilometers per hour. This shows that the sun travels about 17,000,280 kilometers a day.
In the sun, 564 million tons of hydrogen trans-form into 560 million tons of helium every second. The difference of four million tons of gas radiates in the form of energy. In other words, the sun loses four million tons of substance a second, or 240 mil-lion tons a minute. If the sun has been producing energy at this rate for more than three billion years, the matter lost to date is 400,000 million times a mil-lion tons, which is still about 1/5,000 of the sun’s total mass as of today.
Our world has been placed at such a well-calculated distance from this magnificent and enormous source of energy that we are neither vulnerable to its scorching and destructive effects nor destitute of the useful energy it produces. The sun with its magnificent power and energy has been created with such a perfect power and volume that it is most beneficial to every life form on earth, humanity above all, and sends its rays to earth prudently; and this, moreover, for millions of years!
This magnificent sun that we mentioned is only one of about 200 billion stars in the Milky Way gal-axy. In the same manner, the Milky Way is also just one of a couple of hundred billion galaxies that can be seen with modern telescopes. And it takes 100 thousand light years to travel from one side of this Milky Way to the other side. (Light travels at 300,000 kilometers per second.) One must travel 300,000 trillion kilometers to go from the earth to the center of our galaxy, the Milky Way.
A person who thinks long enough along such lines about his surroundings realizes that there is an omniscient and all-powerful creator and that he was not created in vain, but rather there is a reason for his creation. Research shows that all types of religions, from those of primitive societies to the most advanced ones, uphold belief in an all-powerful being.
