What were the scriptures of Abraham, and were they physical?

"The Scriptures of Abraham" (Suhuf Ibrahim) are scriptures that Allah Almighty revealed to His Prophet Abraham, peace be upon him. They contained admonitions and rulings. One must believe in them as part of the divine books revealed by Allah, in fulfillment of His Almighty saying: "The Messenger has believed in what was revealed to him from his Lord, and [so have] the believers. All of them have believed in Allah and His angels and His books and His messengers." As for the nature and content of these scriptures, that is knowledge known only to Allah. No aspect of faith or action depends on knowing it, and delving into it is an unnecessary burden. A "sahifah" (scripture/scroll) is a spread-out thing upon which writing is made, whether it is made of paper, leather, or a tablet.
