1- Do not dispute (with others) lest you will lose splendor and do not joke (with everyone) lest you will be disrespected.
2- As for those who accept to sit in a place other than the first row of a session, Allah and His angels will bless them until they leave that session.
3- Imam Hasan al-Askari (A.S.) answer the man who asked him a miracle or a proof of Imamat: The punishment will be doubled for those who refuted the miracle or proof of Imamat after it had been presented to them according to their demand. He who shows patience will be supplied with the support of Allah. People are accustomed to publicize false missives that they themselves forge. We supplicate to Allah for guiding us (to the right). Matters are either submission or destruction. The end results of everything belong to Allah.
4- Imam al-Askari (A.S.) answered the man who reported to him the disagreement of Shias: Allah has addressed to the intelligent exclusively. People are of different classes: some are the discerning on a way of salvation; they are holding fast to the right and clinging to the branch of the origin; they are neither doubtful not suspicious; they do not consider a shelter other than me. Some are those who have not received the right from its very people; they are like those who embarked on a ship; they ripple when the sea is wavy and calm down when the sea is calm. Some are those who are dominated by the Shaitan; their one and only job is to refute the people of the right and substitute the wrong for the right out of envy. Hence, leave those who went astray to the right and left. When a shepherd wants to gather the hoard, he will not need to exert efforts for so. Beware of divulging our secrets and seeking power, for these two things drive into perdition.
5- Within the unforgivable sins are the sins whose committers wish if they would not commit anything else." Imam al-Askari (A.S.) then said: "Polytheism of people is more hidden that the creeping of ants on a black piece of cloth in a gloomy night.
6- "Bismillah ar Rahman ir Rahim -- in the Name of Allah the Beneficent the Merciful-" is as near to the Great Name (of Allah) as the iris to the white of the eye.
7- In the time of Imam al-Hasan Askari(A.S.), some of the Shias disagreed about his Imamat; therefore the following message was publicized carrying his signature: No one of my fathers suffered the (affliction of the) disagreement of such a group like I did. If this matter of Imamat that you have believed in and embraced is temporary, then I doubt it. If it is as permanent as the affairs of Allah, then what is the meaning of this doubt?
8- The mutual love of the pious. The hate of the sinful to the pious is an advantage for the pious. The hate of the pious to the sinful is debasement for the sinful.
9- To greet everyone you pass by and to sit in a place other than the first class of a session are signs of modesty.
10- Reasonless laughter is a sign of ignorance.
11- Within the misfortunes that deal a death blow is the neighbor who overshadows any good feature that he notices and propagandizes any defect that he notices.
12- Imam al-Askari (A.S.) said to his adherents (Shias) I command you to fear Allah, show piety to your religion, work hard for Allah's sake, tell truths only, return the deposits to their owners whether they are pious or sinful, prostrate yourselves before Allah for a long time, and treat your neighbors courteously. These are the matters that Muhammad (S.A.W.) brought. Offer prayers in the middle of your folks, attend their funeral ceremonies, visit their ill ones, and fulfill their rights. I am pleased if people point to you and say "this is Shi'ite", when you behave piously, tell truths only, return the deposits to their owners, and conduct courteously with people. Fear Allah, be good (examples) and do not be evil. Attract people's fondness of us and save us from every awful character, for we are surely the people of every good thing that is said about us, but we are definitely not the owners of any evil thing that is imputed to us. We enjoy a (distinctive) right in the Book of Allah, a relation (of kinship) to the Messenger of Allah, and a purification whose source is Allah. Only can the liars' claim of enjoying our distinctive features. Refer to Allah very much, refer to death, recite the Quran, and bless the Prophet (S.A.W.). A single blessing of the Prophet (S.A.W.) is ten advantages. Retain the matter of which I have commanded you. Allah keeps you under His supervision. Peace be upon you.
13- Very much offering of prayers and fasting is not the worship; the very worship is the very much pondering over the affairs of Allah.
14- The worst servants - of Allah - are those who are two-faced and two-tongued; they praise their present friends and backbite the absent; they envy them for obtaining graces and disappoint them when they suffer a misfortune.
15- Anger is the key to every evil.
16- In 260 A.H. Imam al-Askari (A.S.) said to his adherents: We have previously ordered you to put the rings in your right hands when we were among you. Now, because you will no longer meet us (normally), we order you to put your rings in your left hands until Allah make your, as well as our, Question prevalent. This is surely the best proof through which you can prove your being loyal to our leadership; i.e. the leadership of the Prophet's family. All the attendants took their rings out of their right hands to put them in the left. The Imam(A.S.) then ordered: Convey this commandment to all of our adherents -Shias.
17- The least comfortable of people is the spiteful.
18- The most pious of people is he who stops at suspicious matters. The best worshipper is he who performs the obligatory religious affairs duly. The most abstinent of people is he who abandons the unlawful. The most hard-working of people is he who deserts sins.
19- You are plunging into decreased deadlines and limited days. He who sows good will harvest delight and he who sows evil will harvest regret. Each cultivator will gain only what he has cultivated. The slow will not gain but his own share. The acquisitive will not catch that which is not his. The source of every advantage is Allah, and the actual protector from every evil is Allah, too.
20- The faithful believer is a blessing for the believers and a claim against he disbelievers.
21- The heart of the foolish is in his mouth and the mouth of the wise is in his heart.
22- The guaranteed sustenance should not engage you from the ordained deed.
23- The excessiveness of the (ritual) ablution is as same as defect.
24- The powerful will be definitely humiliated if he ignores the right and the humble will be definitely valued if he takes in it.
25- Fatigue is the friend of the ignorant.
26- Nothing is above two characters: believing in Allah and benefiting the friends.
27- The babies who dare their fathers will surely treat them impiously when they attain maturity.
28- To show happiness before the grieved is not a sign of good mannerism.
29- Everything that you dislike your life if you lose it is surely preferred to your life, and everything that you desire for death if it befalls you is surely eviler than death.
30- To educate an ignorant and to prevent a habit are two impossible actions.
31- Modesty is an unenviable favor.
32- Do not bestow upon anyone with matters that are difficult for him.
33- Those who advice their friend secretly are respecting them, and those who advice them openly are humiliating them.
34- Allah's favors encompass every misfortune.
35- It is so ugly for a believer to follow a passion that causes him humiliation.
