If you see your muslim brother giving favors to a person because of his wealth, kindly correct him. Meanwhile, the financially poor muslim is to be provided for through zakat as instituted in the Qur'an. We must love for our brother what we love for ourself. You know that every Muslim is the brother of another Muslim. You are all equal.
Nobody has superiority over other except by piety and good action.
There happened to pass by Allah's Apostle a Jew blackened and lashed. Had you not asked me in the name of Allah, I should not have given you this information. So we decided to blacken the face with coal and flog as a substitute punishment for stoning. Hadith - Sahih Muslim, Book 8, Number 3465. Narrated Abdullah ibn Amr ibn al-'As, r.a.
