The Event of Thursday.
Towards the end of the life of the Messenger of Allah ( pbuh&hf ), the Roman army was gathering on the border of the Islamic state, and the Holy Prophet ( pbuh&hf ) ordered all of his companions except Imam 'Ali to leave Madinah and join the batallion of Usama ibn Zayd. Some of the prominent companions refused to join. The Holy Prophet ( pbuh&hf ) ordered them again to go, but they still refused. The third time, when they gathered in his house on Thursday, four days before he ( pbuh&hf ) passed away, and the Holy Prophet ( pbuh&hf ) opened his eyes and saw his companions gathering around his deathbed, he asked for a pen and paper to write his will. One of the companions refused to give them to him, saying: "Verily, pain has overwhelmed him. The book of Allah is enough for us." Once the argument increased, the Holy Prophet ( pbuh&hf ) turned to them and said: "Go away from me. You should not argue in my presence." Sahih Bukhari, 5:177
'Abdullah ibn 'Abbas says: "The disaster struck when they did not allow the Prophet (pbuh&hf) to write his will." al-Milal wal-Nihal, Shahristani, 1:22
Other historians narrate that, on that day, the same companion said: "Leave him (the Holy Prophet) alone. He is hallucinating." Tadhkirat al-Khawass , Sibt ibn al-Jawzi; Sirr al-'Alamin , Abu Hamid al-Ghazali p. 21; Tarikh ibn al-Wardi, 1:21
This situation occurred despite the clear command of the Holy Qur'an: "Obey Allah, and obey the Messenger that you may obtain mercy"Qur'an 4:80
and "He who obeys the Messenger has indeed obeyed Allah, but he who turns away, then we have not sent you (Muhammad) as a watcher over them."Qur'an 3:132
This companion later confessed to his objection to the request of the Holy Prophet ( pbuh&hf ) during the Event of Thursday by saying that the Holy Prophet ( pbuh&hf ) had wanted to mention Imam 'Ali ( pbuh ) for leadership during his sickness, so he stopped him from doing that. Sunan Abi Dawud, 1:98
