He has no need to have a helper. He grants offspring to whoever He desires. He has grace, bounties and mercy. He has granted excellence and exaltation to humans over the rest of the creation. He has granted them understanding and intellect.
Humans have control over the seas, land and the air.
He created humans so that they become viceroys of their Master and Creator on this earth. Humans are the rulers over all life forms on earth and they use them according to their needs and understanding. Being more understanding than the other creatures, it is necessary and compulsory for humans to recognise their Creator, understand His being and attributes, engross themselves in his worship and remembrance, prepare themselves for the life after death and think and worry about what is going to happen after death. It is a grace of the Ruler and Creator that he did not require man to search for truth relying solely on his own intellect but sent messengers for guidance. They educated him to believe in his Ruler and Creator to confess His being and attributes and to worship Him.
