Q. Who wrote the Shahjan-Nama that covers Shah Jahan's entire reign?
Answer: Muhammad Sadiq Khan
Notes: Other than Inayat Khan, another Shahjahan-Nama was written by Muhammad Sadiq Khan, who was a waqia-navis at the Mughal court. Sadiq was a selfless freelance writer who undertook the work just for the love of it and recorded the events of Shah Jahan's reign from the death of Jahangir to the accession of Aurangzeb in an intelligent and impartial manner.
