Allah said "And inside yourselves, do you not observe? وفي أنفسكم أفلا تبصرون؟" (Athariyat 51:21)

Despite the fact that the human body is relatively small and has been studied for thousands of years, we have only been able to interpret less than 1% of our DNA code. If we cannot even understand everything in our small body, how can we claim that we know so much about this universe that someone denies the existence of God beyond our observable universe?

The signs are clear for those who observe and reflect! May Allah make us from those who are thankful to his blessings and guide us all to his path. Go out and use the gift of breathing!
