The qualities of a faithful believer
O’ creatures of Allah! the most beloved of Allah is he whom Allah has given power (to act) against his passions, so that his inner side is (submerged in) grief and the outer side is covered with fear. The lamp of guidance is burning in his heart. He has provided entertainment for the day that is to befall him. He regards what is distant to be near himself and takes the hard to be light. He looks at and perceives; he remembers (Allah) and enhances (the tempo of his) actions. He drinks sweet water to whose source his way has been made easy. So he drinks to satisfaction and takes the level path. He has put off the clothes of desires and got rid of worries except one worry peculiar to him. He is safe from misguidance and the company of people who follow their passions. He has become the key to the doors of guidance, and the lock for the doors of destruction.
He has seen his way and is walking on it. He knows his pillar (of guidance) and has crossed over his deep water. He has caught hold of the most reliable supports and the strongest ropes. He is on that level of conviction which is like the brightness of the sun. He has set himself for Allah, the Glorified, for performance of the most sublime acts of facing all that befalls him and taking every step needed for it. He is the lamp in darkness. He is the dispeller of all blindness, key to the obscure, remover of complexities, and a guide in vast deserts. When he speaks he makes you understand whereas when he remains silent then it is safe to do so. He did everything only for Allah and so Allah also made him His own. Consequently, he is like the mines of His faith and as a stump in His earth. He has enjoined upon himself (to follow) justice.
The first step of his justice is the rejection of desires from his heart. He describes right and acts according to it. There is no good which he has not aimed at nor any likely place (of virtue) of the Qur’an. Therefore the Qur’an is his guide and leader. He gets down when the Qur’an puts down his weight and he settles where the Qur’an settles him down.
The Characteristics of an unfaithful believer
While the other (kind of) man is he who calls himself learned but he is not so. He has gleaned ignorance from the ignorant and misguidance from the misguided. He has set for the people a trap (made) of the ropes of deceit and untrue speech. He takes the Qur’an according to his own views and right after his passions. He makes people feel safe from big sins and takes light the serious crimes. He says that he is waiting for (clarification of) doubts but he remains plunged therein, and that he keeps aloof from innovations but actually he is immersed in them. His shape is that of a man, but his heart is that of a beast. He does not know the door of guidance to follow nor the door of misguidance to keep aloof therefrom. These are living dead bodies.
