None of you will have faith till he wishes for his brother what he likes for himself.
A person asked Muhammad (peace be upon him) "What (sort of) deeds in or (what qualities of) Islam are good?" He replied, "To feed (the poor) and greet those whom you know and those whom you don't know."
All mankind is from Adam and Eve, an Arab has no superiority over a non-Arab nor a non-Arab has any superiority over an Arab; also a white has no superiority over a black nor a black has any superiority over a white - except by piety and good action. Learn that every Muslim is a brother to every Muslim and that the Muslims constitute one brotherhood. Nothing shall be legitimate to a Muslim which belongs to a fellow Muslim unless it was given freely and willingly. Do not therefore do injustice to yourselves. Remember one day you will meet Allah and answer your deeds. So beware: do not stray from the path of righteousness after I am gone.
Prophet Muhammad (peace be upon him)
