Translation of the letter:
One of our helpers informed us, he said: I wrote Mansoor Hashimi Khorasani, may God Almighty support him, and asked him to write me every action that I must do after recognizing the truth and supporting it to be among the successful. So he wrote me:
“And as to what follows...
 Perform the prayer at its initial time.
 Do not abandon the Nafilah of night, and seek forgiveness at dawn.
 If you are able to not neglect the remembrance of God even for a moment, then do so; because neglecting his remembrance is the root cause of every sin.
 Remember death often, and go visit the graves; because you will not stay on the earth but for a short time.
 Fast on the first and last Thursday and the middle Wednesday of each month; because this is a Sunnah.
 Give alms; because it atones for your sins.
 Do good to your parents, even if they offend you; because they have done good to you well enough.
 Do not sever your kinship ties, even if it is hung by a strand of hair.
 Do not lie, unless you fear that you will be killed or get somebody killed.
 Do not backbite, unless about someone who is an infidel or a sinner. So when you complain about others in their absence, say: Those who do such or say such, and do not mention their name.
 Do not argue, even if you are right, rather bring your proof and keep quiet, even if you are accused of being defeated.
 Admit your mistake, despite your aversion.
 Forbid every wrong deed that you see, and enjoin every right deed that you do not see. This is the key to reform the world.
 Do not speak too much in order to stay safe; because speaking too much is not without faults.
 Do not joke, unless you say the truth.
 Do not insult or defame anyone, even if he is worthy of death.
 Fulfill your promise, even if it is to a child.
 Do not disgrace any believer; because you will be disgraced.
 Do not become angry, unless you restrain it; because anger is a gate of the gates of Hell.
 Do not be strict with people so that they will not be strict with you; that is, do not find fault, scrutinize, gloat and retaliate.
 Do not entrust your works to others, unless you are helpless.
 Do not fill your stomach, and do not eat what is not suitable for your temperament.
 Your sexual instinct is a hungry and sleeping monster. Beware, do not awake it because it will eat you.
 Do not express an opinion about what you have no knowledge of, because you will say unreasonable words.
 Do not sleep less than five hours and more than eight hours; because you will harm yourself.
 Do not retell any news that you hear, because it may be a lie.
 Your time is more valuable than a diamond. So do not spend it on games and works that are useless.
 You have to study; because there are still many things that you do not know.
 You have to do exercise; because a strong believer is better than a weak believer.
 Be clean and well-groomed, even if you wear a newspaper.
I ask God for success and forgiveness for myself and you, and peace be upon you and upon whoever follows the guidance”.
