All perfect praise be to Allaah, The Lord of the Worlds. I testify that there is none worthy of worship except Allaah, and that Muhammad 
  is His slave and Messenger. 
We did not understand what the questioner meant by 'the paper'; if he meant the sheet which 'Ali 
  was informed about and which he used to hang beside his sword, then this is a paper on which the ages of camels that were taken for Zakah (obligatory charity) were written, and on which the blood money was recorded, and a narration of the Prophet, sallallaahu ‘alayhi wa sallam, about the excellence of Madeenah in which he, sallallaahu ‘alayhi wa sallam, said: "Madeenah is a sacred between the mountains of 'Ayr and Thawr."
The content of this sheet, exactly as we mentioned, was narrated by Muslim
. There is nothing in it which the Prophet, sallallaahu ‘alayhi wa sallam, gave as a special secret to 'Ali 
  but not to others. Indeed 'Ali 
  said, "Whoever claims that I have something to read other than the Book of Allaah and this paper, then he is indeed a liar." [Muslim] 
Allaah Knows best.
