It is recorded in Safinat’ul-Bihār that Imam Mūsa Ibn Ja’far (a.s) said Salām to a black Sudanese as he passed by him. Then he went near him and spoke with him for sometime. After that he said: Tell me if there is anything I can do for you. People said: O son of the Messenger! You go towards such a person and ask about his needs while he is more needful than you? Imam (a.s.) said:
He is a servant of Allah (S.w.T.) too and our brother in faith. Both of us have got the best father, Hazrat Adam, the father of humanity and both of us are bestowed with Islam, the best religion. May be time would render us more needful than him so why should we feel proud of ourselves?
