Ibn Abbas said, "Thursday, and what a Thursday!" Then he wept until his tears moistened the pebbles. On another occasion, he said his tears flowed onto the pebbles.We asked, "Abu Abbas, what about Thursday?"He said, "The Messenger of Allah's ﷺ illness grew severe, and he said, 'Bring me writing materials so I may write for you a document after which you will never go astray.' But they began to dispute, and disputing is not fitting in the presence of a prophet. They said, 'What is the matter with him? Has he become delirious?'" Sufyan said, meaning he was speaking incoherently. "They said, 'Ask him to clarify.' So they went back to question him again, but he said, 'Leave me. The state I am in is better than what you are calling me to.' Then he commanded three things." Sufyan once said, "He gave instructions concerning three things." He said, "Expel the polytheists from the Arabian Peninsula, and grant gifts to delegations as I used to grant them."Saeed remained silent about the third instruction, so I do not know whether he kept silent about it deliberately, and on another occasion he said, "or he forgot it." Sufyan once said, "Either he left it out or forgot it."
حدثنا سفيان عن سليمان بن أبي مسلم خال ابن أبي نجيح سمع
ابن عباس يوم الخميس وما يوم الخميس ثم بكى حتى بل دمعه وقال مرة دموعه الحصى قلنا يا أبا العباس وما يوم الخميس قال اشتد برسول الله ﷺ وجعه فقال ائتوني أكتب لكم كتابا لا تضلوا بعده أبدا فتنازعوا ولا ينبغي عند نبي تنازع فقالوا ما شأنه أهجر قال سفيان يعني هذى استفهموه فذهبوا يعيدون عليه فقال دعوني فالذي أنا فيه خير مما تدعوني إليه وأمر بثلاث وقال سفيان مرة أوصى بثلاث قال أخرجوا المشركين من جزيرة العرب وأجيزوا الوفد بنحو ما كنت أجيزهم وسكت سعيد عن الثالثة فلا أدري أسكت عنها عمدا وقال مرة أو نسيها وقال سفيان مرة وإما أن يكون تركها أو نسيها
Its isnad is sahih. Sulayman bin Abu Muslim is Sulayman al-Ahwal al-Makki, and he is trustworthy, as Ahmad said. Bukhari related the hadith at 6:118, 195 and 8:100-103, and it is explained in Fath al-Bari at the last location. As for his statement, "Is he delirious," Ibn Uyayna explained it as meaning he was raving, and in Nihaya it is said to mean, has his speech become confused because of the illness he has, as a form of questioning, that is, has his speech changed and become jumbled on account of his sickness.As for the third bequest, about which Saeed bin Jubayr remained silent, it was either the bequest concerning the Quran, or the dispatch of Usama's army, or his statement, "Do not take my grave as an idol," or his statement, "Prayer, and those whom your right hands possess." He did in fact enjoin all of these in sahih hadiths, see Fath al-Bari. Ibn Saad related it at 2/2/36 from Sufyan bin Uyayna with this same isnad. Ibn Kathir mentioned it in Tarikh at 5/227 from Bukhari and also attributed it to Muslim. See 2374, 3111. And see what will come at 2676, 2992.
