(i) Narrated ‘Abdullah bin ‘Umar: The Prophet said, “A man keeps on asking others for something till he comes on the Day of Resurrection without any piece of flesh on his face.” The Prophet added, “On the Day of Resurrection, the Sun will come near (to, the people) to such an extent that the sweat will reach up to the middle of the ears, so, when all the people are in that state, they will ask Adam for help, and then Moses, and then Muhammad (p.b.u.h).” The sub-narrator added “Muhammad will intercede with Allah to judge amongst the people. He will proceed on till he will hold the ring of the door (of Paradise) and then Allah will exalt him to Maqam Mahmud (the privilege of intercession, etc.). And all the people of the gathering will send their praises to Allah. (Sahih Al-Bukhari, Volume 2, Book 24, Number 553)
(II) Abu Huraira reported Allah’s Messenger (may peace be upon him) as saying: I shall be pre-eminent amongst the descendants of Adam on the Day of Resurrection and I will be the first intercessor and the first whose intercession will be accepted (by Allah). (Sahih Muslim, Book 030, Number 5655)
(i) Here Muhammad wish to become an intercessor :
Narrated Abu Huraira:
Allah’s Apostle said, “For every Prophet there is one invocation which is definitely fulfilled by Allah, and I wish, if Allah will, to keep my that (special) invocation as to be the intercession for my followers on the Day of Resurrection.”
(Sahih Al-Bukhari, Volume 9, Book 93, Number 566)
(ii) I am a Prophet of Allah but I do not know what will be my end.
( Sahih Bukhari, Chapter “Al-Janaiz” Volume 2, Book 23, Number 334)
(iii) O people of Quraish be prepared for the hereafter, I cannot save you from the punishment of Allah; O Bani Abd Manaf, I cannot save you from Allah; O Abbas, son of Abdul Mutalib, I cannot protect you either; O Fatima, daughter of Muhammad, even you I cannot save.
(Sahahin) [1]
(iv)Narrated Abu Huraira: The Prophet said, "(On the Day of Resurrection) camels will come to their owner in the best state of health they have ever had (in the world), and if he had not paid their Zakat (in the world) then they would tread him with their feet; and similarly, sheep will come to their owner in the best state of health they have ever had in the world, and if he had not paid their Zakat, then they would tread him with their hooves and would butt him with their horns." The Prophet added, "One of their rights is that they should be milked while water is kept in front of them." The Prophet added, "I do not want anyone of you to come to me on the Day of Resurrection, carrying over his neck a sheep that will be bleating. Such a person will (then) say, 'O Muhammad! (please intercede for me,) I will say to him. 'I can't help you, for I conveyed Allah's Message to you.' Similarly, I do not want anyone of you to come to me carrying over his neck a camel that will be grunting. Such a person (then) will say "O Muhammad! (please intercede for me)." I will say to him, "I can't help you for I conveyed Allah's message to you."
