Allah will make Hazrat Mahdi (as) his instrument to prepare perfect books that influence his time and the entire world

Abu Bashir says: It is narrated from Imam Muhammad Bakr or Imam Jaffar Sadik that: “HE WHO GIVES HIM [HAZRAT MAHDI (AS)] IMAMATE WILL GIVE HIM KNOWLEDGE AND BOOKS AND WILL NOT LEAVE HIM ALONE.” (Sheikh Muhammad ibn Ibrahim Numani, al-Ghaybah al-Numani, p. 387)

It transpires from the hadith that Hazrat Mahdi (as) will be constantly under the control of Almighty Allah, and that Allah will make Hazrat Mahdi (as) His instrument in preparing perfect books that will influence his time and the entire world.
