Two Questions On The Most Merciful
A superlative degree is used to tell the highest possible degree one may imagine. It is not necessary to have one similar in comparison. Here the comparison is with his creations who have very lesser degrees of his attributes. Humans do not believe in the seen only. Experience and observations lead us to believe in unseen objects and theories that come true later. Viruses and atoms are not seen yet but they are believed to be existing for their attributes. The magnetic field cannot be seen but believed for its existence. God is believed for His signs and the believability of his religion which is a separate topic. Seeing is not essential. God will throw into hell only those who have no genuine excuse for their denial of the truth. Humans can deny a reality as iblees did. This is arrogance and this kind of arrogance deserves eternal hell.
