Advice to one of his sons after returning from the Battle of Siffin

what has not at all come to you. Infer about what has not yet happened from what has already happened, because occurrences are ever similar. Do not be like those whom preaching does not benefit unless you inflict pain on them, because the wise take instruction from teaching while beasts learn only from beating. Ward off from yourself the onslaught of worries by firmness of endurance and purity of belief. He who gives up moderation commits excess. A companion is like a relation. A friend is he whose absence also proves the friendship. Passion is a partner of distress. Often the near ones are remoter than the distant ones, and often the distant ones are nearer than the near ones. A stranger is he who has no friend. He who transgresses right narrows his own passage. He who stays in his position remains constant upon it. The most trustworthy intermediary is that which you adopt between yourself and Allah the Glorified. He who does not care for your interests is your enemy. When greed leads to ruin deprivation is an achievement. Not every defect can be reviewed, and not every opportunity recurs. Often a person with eyes misses the track while a blind person finds the correct path. Delay an evil because you will be able to hasten it whenever you desire. The disregard of kinship of the ignorant is equal to the regard for kinship of the wise. Whoever takes the world to be safe, it will betray him. Whoever regards the world as great, it will humiliate him. Every one who shoots does not hit. When authority changes, the time changes too. Consult the friend before adopting a course and the neighbour before taking a house. Beware, lest you mention in your speech what may rouse laughter even though you may be relating it from others. Do not consult women because their view is weak and their determination unstable. Cover their eyes by keeping them under the veil because strictness of veiling keeps them for long. Their coming out is not worse than your allowing an unreliable man to visit them. If you can manage that they should not know anyone other than you, do so. Do not allow a woman matters other than those about hereself, because a woman is a flower not an administrator. Do not pay her regard beyond herself. Do not encourage her to intercede for others. Do not show suspicion out of place, because this leads a correct woman to evil and a chaste woman to deflection. For everyone among your servants fix a work for which you may hold him responsible. In this way, they will not fling the work one over the other. Respect your kinsmen because they are your wings with which you fly, the origin towards which you return and your hands with which you attack. Place your religion and your world at Allah's disposal and beg Him to ordain the best for you in respect of the near and the far, this world and the next; and that is an end to the matter.
