Signs of Allah in the systems of the Universe

The planet and the whole universe in which we live bear all the properties necessary for our lives. Someone who thinks about this will see clearly that Allah created the whole universe for us

Man, for example, can breathe effortlessly all the time. The air he inhales neither burns his nasal passages nor makes him dizzy nor causes headaches. The proportion of the gases in air is designed with the amounts that are most suitable for the human body.

If the oxygen concentration in the atmosphere were a little more or a little less than at present, in both cases life would vanish. He then remembers what a hard time he has in breathing in airless places. As a believing person continues to think on this subject, he constantly gives thanks to his Lord.
