10. Muhammad ibn Yahya has narrated from Ahmad ibn Muhammad from Ahmad ibn Muhammad ibn abu Nasr who has said the following: “Once I asked abu al-Hassan al-Rida  a question. He refrained silently and said, ‘If we give you everything you want, it may become evil for you and the neck of the owner of this cause will be caught tight.’ “Abu Ja’far  has said, ‘It is the guardianship of Allah, Who told it secretly to Jibril, who secretly told it to Muhammad  who secretly told it to Ali  who secretly told it to whoever Allah wanted and then you publicize it. Who is he that has heard a word then has held it secretly?’ “Abu Ja’far  has said, ‘It is in the wisdom of ‘Ale Dawud (family of David), “It is necessary for a Muslim to have control over his soul, be attentive to his affairs and have foil knowledge of the people of his time.” Be pious before Allah and do not publicize our Hadith. It is a fact that Allah defends his friends and exacts recompense for His friends from His enemies. Have you considered how Allah dealt with Ale Barmak (family of Barmak) and how He recompensed for abu al-Hassan  when banu ‘Ash’ath faced the great danger and Allah defended them for their supporting abu al- Hassan ? In Iraq you are well aware of the deeds of those Pharaohs and the respite that Allah has given them. Therefore, you must observe piety before Allah and do not allow the worldly life to deceive you. Do not be confused about those who have been given respite. It is as if the matter (reappearance of al-Mahdi ) is almost within your reach.’”
