Hazrat Abdullah bin Zumrah (may Allah have mercy on him) narrates that Hazrat Ka'b (may Allah be pleased with him) said: Whoever establishes prayer and pays zakat, and listens and obeys, indeed his faith is of a moderate level. And whoever loves for the sake of Allah, and hates for the sake of Allah, and gives for the sake of Allah, and withholds for the sake of Allah, indeed his faith has become complete.
