The word “کریم“, “Karim” means a person who helps others and gives to them without any expectations.
All creatures are needy because they are bounded and limited. Therefore, all the actions of creatures are for satisfying their needs.
When a creature gives or helps, he certainly expects that one of his needs to be satisfied. In fact, he makes a deal. However, God is needless, and he is the only giver and helpers who gives and helps without any expectations.
