What is meant by, "Whoever perfects that which is between him and God, God will suffice him for that which is between him and the people"?

The meaning of "Whoever rectifies what is between him and Allah, Allah will rectify what is between him and the people" is that whoever obeys Allah, fulfills what He has obligated upon him, and excels in it, Allah will suffice him in what is between him and the people by turning their hearts towards him and warding off their harm from him. Thus, the rectification of a servant's condition and his happiness with people lies in Allah's pleasure. And the fortunate one is he who deals with people for the sake of Allah, treats them well for the sake of Allah, and fears Allah in his dealings with them.
