to one of his companions, ?O servant of Allah! Love for the sake of Allah and hate for the sake of Allah, and befriend for the sake of Allah and contest for the sake of Allah, for Allah's guardianship is attained only by that, and man will not find the taste of faith though his prayers and fasting be much unless he behaves thus. In this present day, the brotherhood and friendship of the people are mainly for the sake of this world; they love each other for its sake and hate each other for its sake.'
