From time and again some people who just out of malice want to attack the Companions the Prophet (saw) [May Allah (swt) be pleased with them all] and claim that some of the Prominent among them did not attend Prophet (saw)’s funeral service. For the record I am cutting and pasting the following form the Net.
Let’s just try to keep the discussions healthy - Please
The Last Day Alive:
In a narration by Anas bin Malik, he said: “While the Muslims were performing the dawn prayer on Monday — led by Abu Bakr, they were surprised to see the Messenger of Allâh raising the curtain of ‘Aishah’s room. He looked at them while they were praying aligned properly and smiled cheerfully. Seeing him, Abu Bakr withdrew to join the lines and give way to him to lead the prayer. For he thought that the Prophet wanted to go out and pray.” Anas said: “The Muslims, who were praying, were so delighted that they were almost too enraptured at their prayers. The Messenger of Allâh made them a gesture to continue their prayer, went into the room and drew down the curtain.”
The Messenger of Allâh did not live for the next prayer time.
When it was daytime, the Prophet called Fatimah and told her something in a secret voice that made her cry. Then he whispered to her something else which made her laugh. ‘Aishah enquired from her after the Prophet’s death, as to this weeping and laughing to which Fatimah replied: “The first time he disclosed to me that he would not recover from his illness and I wept. Then he told me that I would be the first of his family to join him, so I laughed.”
He gave Fatimah glad tidings that she would become the lady of all women of the world.
Fatimah witnessed the great pain that afflicted her father. So she said: "What great pain my father is in!” To these words, the Prophet remarked:
“He will not suffer any more when today is over.”
He asked that Al-Hasan and Al-Husain be brought to him. He kissed them and recommended that they be looked after. He asked to see his wives. They were brought to him. He preached them and told them to remember Allâh. Pain grew so much severe that the trace of poison he had at Khaibar came to light. It was so sore that he said to ‘Aishah: “I still feel the painful effect of that food I tasted at Khaibar. I feel as if death is approaching.”
He ordered the people to perform the prayers and be attentive to slaves. He repeated it several times.
The Prophet breathes his Last:
When the pangs of death started, ‘Aishah leant him against her. She used to say: One of Allâh’s bounties upon me is that the Messenger of Allâh died in my house, while I am still alive. He died between my chest and neck while he was leaning against me. Allâh has mixed his saliva with mine at his death. For ‘Abdur Rahman — the son of Abu Bakr — came in with a Siwak (i.e. the root of a desert plant used for brushing teeth) in his hand, while I was leaning the Messenger of Allâh against me. I noticed that he was looking at the Siwak, so I asked him — for I knew that he wanted it — “Would you like me to take it for you?” He nodded in agreement. I took it and gave it to him. As it was too hard for him, I asked him “Shall I soften it for you?” He nodded in agreement. So I softened it with my saliva and he passed it (on his teeth).
In another version it is said: “So he brushed (Istanna) his teeth as nice as he could.” There was a water container (Rakwa) available at his hand with some water in. He put his hand in it and wiped his face with it and said:
“There is no god but Allâh. Death is full of agonies.”
As soon as he had finished his Siwak brushing, he raised his hand or his finger up, looked upwards to the ceiling and moved his lips. So ‘Aishah listened to him. She heard him say: “With those on whom You have bestowed Your Grace with the Prophets and the Truthful ones (As-Siddeeqeen), the martyrs and the good doers. O Allâh, forgive me and have mercy upon me and join me to the Companionship on high.”] Then at intervals he uttered these words: “The most exalted Companionship on high. To Allâh we turn and to Him we turn back for help and last abode.” This event took place at high morning time on Monday, the twelfth of Rabi‘ Al-Awwal, in the eleventh year of Al-Hijrah. He was sixty-three years and four days old when he died.
The Companions’ concern over the Prophet’s Death:
The great (loss) news was soon known by everybody in Madinah. Dark grief spread on all areas and horizons of Madinah. Anas said:
“I have never witnessed a day better or brighter than that day on which the Messenger of Allâh came to us; and I have never witnessed a more awful or darker day than that one on which the Messenger of Allâh died on.”
When he died, Fatimah said: “O Father, whom his Lord responded to his supplication! O Father, whose abode is Paradise. O Father, whom I announce his death to Gabriel.”
‘Umar’s Attitude:
‘Umar, who was so stunned that he almost lost consciousness and stood before people addressing them: “Some of the hypocrites claim that the Messenger of Allâh died. The Messenger of Allâh did not die, but went to his Lord in the same way as Moses bin ‘Imran did. He stayed away for forty nights, but finally came back though they said he had been dead. By Allâh, the Messenger of Allâh will come back and he will cut off the hands and legs of those who claim his death.”
Abu Bakr’s Attitude:
Abu Bakr left his house at As-Sunh and came forth to the Mosque on a mare-back. At the Mosque, he dismounted and entered. He talked to nobody but went on till he entered ‘Aishah’s abode, and went directly to where the Messenger of Allâh was. The Prophet was covered with a Yemeni mantle. He uncovered his face and tended down, kissed him and cried. Then he said: “I sacrifice my father and mother for your sake. Allâh, verily, will not cause you to die twice. You have just experienced the death that Allâh had ordained.”
Then he went out and found ‘Umar talking to people. He said: “‘Umar, be seated.” ‘Umar refused to do so. People parted ‘Umar and came towards Abu Bakr, who started a speech saying:
“And now, he who worships Muhammad . Muhammad is dead now. But he who worships Allâh, He is Ever Living and He never dies. Allâh says:
‘Muhammad ( )is no more than a Messenger, and indeed (many) Messengers have passed away before him. If he dies or is killed, will you then turn back on your heels (as disbelievers)? And he who turns back on his heels, not the least harm will he do to Allâh, and Allâh will give reward to those who are grateful.’” [3:144]
Ibn ‘Abbas said: “By Allâh, it sounded as if people had never heard such a Qur’ânic verse till Abu Bakr recited it as a reminder. So, people started reciting it till there was no man who did not recite it.”
Ibn Al-Musaiyab said that ‘Umar had said: “By Allâh, as soon as I heard Abu Bakr say it, I fell down to the ground. I felt as if my legs had been unable to carry me so I collapsed when I heard him say it. Only then did I realize that Muhammad had really died.”
Enter Abu Bakr
As they wavered between believing Umar or the indubitable meaning of the women's crying, Abu Bakr heard the news and returned from al Sunh. He looked through the door of the mosque and saw the Muslims being addressed by Umar, but he did not tarry there. He went straight to the quarters of A'ishah and asked for permission to enter. He was answered that there was no need that day for permission. He entered and found the Prophet laid down in a corner and covered with a striped cloth. He approached, uncovered the face and kissed it, saying, "How wholesome you are, whether alive or dead!" He then held the Prophet's head in his hands and looked closely at the face which showed no sign whatever of death's attack. Laying it down again, he said, "What would I not have sacrificed for you! The one death which God has decreed for you, as for any other man, to taste, you have now tasted. Henceforth, no death shall ever befall you." He covered the head with the striped cloth and went straight to the mosque where Umar was still proclaiming loudly that Muhammad had not died. The crowds made a way for him to the front, and as he came close to Umar he said to him "Softly, O Umar ! Keep silent!" But Umar would not stop talking and continued repeating the same claim. Abu Bakr rose and made a sign to the people that he wished to address them. No one could have dared impose himself upon the congregation in such manner except Abu Bakr, for he was the ever trustworthy friend of the Prophet, whom Muhammad would have chosen from among all men. Hence, it was natural that the people hastened to respond to his call and move away from Umar.
Muhammad Is Truly Dead
After praising and thanking God, Abu Bakr delivered the following brief address: “O Men, if you have been worshipping Muhammad, then know that Muhammad is dead. But if you have been worshipping God, then know that God is living and never dies.” He then recited the Qur’anic verse:
“Muhammad is but a prophet before whom many prophets have come and gone. Should he die or be killed, will you abjure your faith? Know that whoever abjures his faith will cause no harm to God, but God will surely reward those who are grateful to him.” [Qur’an, 3:144]
Realizing that the people were withdrawing from him and going to Abu Bakr, Umar fell silent and listened to Abu Bakr's speech. Upon hearing Abu Bakr recite the Qur'anic verse, Umar fell to the ground. The certainty that the Prophet of God was truly dead shattered him. Beguiled by `Umar’s speech, the people listened to Abu Bakr’s statement and to the Qur’anic verse as if it was given to them for the first time. They had forgotten that there was any such revelation. Abu Bakr’s stark words dissipated all doubt and uncertainty. His Qur’anic quotation reassured the Muslims that their holding fast to God Who never dies would more than compensate for Muhammad’s passing.
