Mishkat al-Masabih 94

‘Ubada b. as-Samit reported God’s messenger as saying, “The first thing God created was the pen. He told it to write and when it asked Him what it should write He told it to write what was decreed, so it wrote what had taken place and what would take place to all eternity.” Tirmidhi transmitted it, saying that this is a tradition whose isnad is gharib.
