Guy converts to Islam after a wolf ate his sheep, and told him to convert to Islam

Bukhari, Volume 3, Book 39, Number 517:

Narrated Abu Huraira:The Prophet said, "While a man was riding a cow, it turned towards him and said, 'I have not been created for this purpose (i.e. carrying), I have been created for sloughing." The Prophet added, "I, Abu Bakr and 'Umar believe in the story." The Prophet went on, "A wolf caught a sheep, and when the shepherd chased it, the wolf said, 'Who will be its guard on the day of wild beasts, when there will be no shepherd for it except me?' "After narrating it, the Prophet said, "I, Abu Bakr and 'Umar too believe it." Abu Salama (a sub-narrator) said, "Abu Bakr and 'Umar were not present then." (It has been written that a wolf also spoke to one of the companions of the Prophet near Medina as narrated in Fatah-al-Bari:

Narrated Unais bin 'Amr: Ahban bin Aus said, "I was amongst my sheep. Suddenly a wolf caught a sheep and I shouted at it. The wolf sat on its tail and addressed me, saying, 'Who will look after it (i.e. the sheep) when you will be busy and not able to look after it? Do you forbid me the provision which Allah has provided me?' " Ahban added, "I clapped my hands and said, 'By Allah, I have never seen anything more curious and wonderful than this!' On that the wolf said, 'There is something (more curious) and wonderful than this; that is, Allah's Apostle in those palm trees, inviting people to Allah (i.e. Islam).' "Unais bin 'Amr further said, "Then Ahban went to Allah's Apostle and informed him what happened and embraced Islam.)" palm trees or other trees and share the fruits with me."

1) What religious purpose existed for the cow telling a person that he was not for riding?
a) Where does one find a talking cow?
b) Do cows talk if you ride them?
c) Was the purpose of the talking cow an endorsement for Hinduism, and its reverence for the bovine nation?
d) Do cows worship Allah, Krishna or any deity?

2) Why would Mohammad add "I, Abu Bakr and 'Umar too believe it" when they were not there?
a) Did Mohammad need the endorsement of people to verify his stories?
b) COuld Umar and Abu Bakr only believe this story when they were not present, and would not die of laughter if they were there?

3) The following passage spoken by the wolf is disturbing: 'Who will be its guard on the day of wild beasts, when there will be no shepherd for it except me?'
a) Does that mean that humanity will end?
b) Does that mean that Allah is so cruel, that once humanity ends, he will entrust sheep to wolves, so they may be slaughtered?
c) Is this a subversive reference to the slaughter of Christians, as Jesus was called "Lamb of God"; or is it a subversive reference to Christians living under Islamic countries (i.e. the Ottoman Empire whose symbol was a wolf, and was entrusted to look after Christians, and did so by committing mass genocide?)

4) This passage spoken by the wolf in the second paragraph makes no sense: 'There is something (more curious) and wonderful than this; that is, Allah's Apostle in those palm trees, inviting people to Allah (i.e. Islam).'
a) Why would a wolf eat some guy's sheep and tell him to follow Allah's apostle?
i) Was it so the wolf could eat more sheep?
b) Why would the shephard follow the advice of a wolf who just ate his sheep, and effectively made him poorer?
c) Was the shephard dumb?
d) Who follows the advice of a person that just screwed them, especially in converting to a religion advocated that animal that screwed them?

5) What is more curious than a talking wolf? Mohammad under date trees inviting people to Allah...

6) Finally, did Bukhari include this passage to show that it is a curious thing how anyone could follow Mohammad?
a) Or did he include this to show that following Mohammad will cause one to lose their belongings to the proverbial wolf?
