Sahih al-Bukhari 58:10

that he heard Ibn `Abbas saying, "Thursday! And you know not what Thursday is? After that Ibn `Abbas wept till the stones on the ground were soaked with his tears. On that I asked Ibn `Abbas, "What is (about) Thursday?" He said, "When the condition (i.e. health) of Allah's Messenger (ﷺ) deteriorated, he said, 'Bring me a bone of scapula, so that I may write something for you after which you will never go astray.'The people differed in their opinions although it was improper to differ in front of a prophet, They said, 'What is wrong with him? Do you think he is delirious? Ask him (to understand). The Prophet (ﷺ) replied, 'Leave me as I am in a better state than what you are asking me to do.' Then the Prophet (ﷺ) ordered them to do three things saying, 'Turn out all the pagans from the Arabian Peninsula, show respect to all foreign delegates by giving them gifts as I used to do.' " The sub-narrator added, "The third order was something beneficial which either Ibn `Abbas did not mention or he mentioned but I forgot.'
