Be a human who is always grateful

The Prophet SAW, is a role model for us. Always give an example that we do good to others. Regardless of who he is, do good with sincerity without expecting anything. But sometimes we ordinary people, who are weak with deception, have once become angry, sad, disappointed and even hate when doing good with someone. That's when we once needed someone's help. But let alone help instead turn away, as if we have no meaning. Then we get angry, disappointed and hate or even revenge and regret often help. Like he forgot our helping hand before. Do our rewards do it in vain first? What is our help that used to be now strings attached. The answer is don't depend / hope on humans. Because God is the best helper. Ask to Allah, because Allah is the Mover of the hearts of men. We ask for help from one people, but Allah actually sends help through other people. The point is Khusnuzan with Allah.
