I do not know about that hadith but i have heard this hadith many times.
couldn't find an English translation so i used the google translator
Saqr bin Abi Delf Karkhi said: Because Mutawakkul arrested Imam Hadi Askari (peace be upon him), I came to get the news, Razqi, who was Mutawakkul's doorman, looked at me and ordered me to be taken to him.
When they took me to him, he said to me: "O Saqr, what have you been doing?" I said: "O master, it's fine." He said to sit down, and he asked me about the past and the near past.
The people scattered around him, then he said to me: What were you doing and why did you come? I said: It is for a good cause. He said: Maybe you came to ask about your master. I said: Who is my master? My master is Amir al-Mu'minin, he said: Be quiet, your master is on the right, don't be afraid of me because I am on your religion, I said: Thank God, he said: Do you want to see him? I said: Yes, he said: Sit until the mail carrier leaves in front of him
I sat down, and when he came out, he said to his slave: Take Saqr's hand and take him to the room where Alavi is a prisoner and leave him alone with him. He says: He took me to the cell where Alavi was and He pointed to a house, so I entered and saw that the imam was sitting on a mat and a grave had been dug in front of him.
I greeted and he answered my greeting and ordered me to sit down, then he said to me: O Saqr, what made you come? I said: My lord, I came to hear from you, then I looked at the grave and wept. He looked at me and said: Don't be sad, they can't hurt me right now, I said: I thank God, then I said: My Lord! A hadith was narrated from the Messenger of God (peace and blessings of God be upon him) that I do not know the meaning of, he said: What is it? I said: It is the sentence that says, "Don't take the days as enemies because they will take you as enemies." What does that mean?
He said: Yes, we are the days as long as the heavens and the earth are standing. Saturday is the name of the Prophet of God, and Saturday is an allusion to the Commander of the Faithful, and Monday is Hasan and Hussein, and Tuesday is Ali bin Al-Hussein, Muhammad bin Ali, and Jafar bin Muhammad, and Wednesday is Musa. There are Ibn Jafar, Ali Ibn Musa, Muhammad Ibn Ali and I, and Thursday is my son Hasan Ibn Ali, and Friday is the son of my son, and the companions of the truth gather around him, and he is the one who fills the earth with justice and peace, just as It has been full of cruelty and oppression. This was the meaning of the days, so don't make them enemies in this world because they will make you enemies in the Hereafter, then he said: Say goodbye and go out because I fear for your safety.
