in order to answer diamant, im going to use my older account......
first of all, i would like to point out to the fact that what she has provide is only a copy and paste from the so called "knowldgable" people of their sect, so any problems found in her answer can not be ignored by excuses which blame her lack of knowldge......
in her copy and paste, they claim how the hadith recorded in trimidhi is "weak", but it seems like they have not seen the version of alHakim alNaysaburi, alMustadrak `ala al-Sahihayn where he insists on how the hadith is sahih based on the method of bukhari and muslim.....
she says that Prophet (s) mentioned Quran and Sunan in the last hajj, but when it came to Khum, Prophet (s) mentioned Quran and Ahl-ul-bait (as) since people who were going to medina were there so thats what He (s) said......
she needs to realize 2 things here, one that by saying this she;s making the Prophet (s) sound like He (s) countradcited Himself (AstaghfureAllah)
how can the Prophet (s) in the last hajj tell people it's Quran and Sunna but in Khum say it's Quran and Ahl-ul-bait (as)?
so did Prophet (s) order different things and contradicted himself?
indeed no
this is the 2nd point
even in the last Hajj Prophet (s) mentioned Quran and Ahl-ul-bait (as)
....Jabir ibn `Abd Allah said: "I saw the Messenger of Allah - upon whom be God's peace and benedictions - in the course of his hajj pilgrimage on the day of `Arafah. The Prophet (S) was seated on his camel, alQaswa', and was delivering a sermon. I heard him say: 'O people, I am leaving among you that which if you hold on to you shall never go astray: the Book of Allah and my kindred, my household."

we all know the Prophet (s) also mentioned Quran and Ahl-ul-bait (as) AGAIN in Ghadir
Prophet (s) had once again reminded people about these 2 in the Mosque of Medina
and once again on the His deathbed........
and we all know how omar disoabyed, opposed and insulted The Prophet (s) on His deathbed when He (s) wanted to put these 2 on paper....
now what is more intresting is diamant claims the hadith about Quran and Sunna is the one being mentioned in the last hajj, but
1. this hadith has ONLY been mentioned by sunnis and is NOT recorded by Shias, unlike the other version which is reported by BOTH Shias and Sunnis
2. even BOTH muslim and bukhari have AVOIDED recording the hadith about Quran and Sunna
diamant also goes on to say how Shias are not reliable.......
but they have forgoten that even in bukhari and muslim there are hadiths which include chains of Shias......
......some who were known to be extreamist and would not let people called "muawia" to enter their homes!
so i would like to ask the following Questions.......
1. if Prophet (s) mentioned Quran and Sunna in hajj, which as they claim it was mentioned in front of a lot more people, then how come the Sahihayn have not recorded such important hadith?
2. if Prophet (s) mentioned Quran and Sunna, then why didn't He (s) mention "Sunna" in Ghadir? wasn't the "Sunna" something that those people should had followed? (please note Prophet [s] ONLY mentions leaving us 2 things, Quran and Ahl-ul-bait [as])
3. if as you say the event of Ghadir Khom was because of some argument between Imam Ali (as) and some other people, then why did Prophet (s) kept thousends of people in that hot weather for 3 days and made them give baya to Imam Ali (as)?
4. what was the writing of Prophet (s) going to be on His deathbed which would keep us away from going astray?
5. why didn't umar say anything when abu bakr was saying his will on his deathbed?
6. even if as you try to mislead people, for the sake of argument, we say Prophet (s) was only talking about the "behaviour" of people towards the Ahl-ul-bait (as), then why did abu bakr take away Fadak From Bibi Fatima (as) and made Her (as) angry at himself? why did omar play the whole "give baya or die" method with the Ahl-ul-bait (as)? was this the kind of behaviuor Prophet (s) was talking about?
7. on the deathbed of Prophet (s) when He (s) asked for pen and paper and when omar acted that way and said Quran is enough for us, why didn't he mention anything about "Sunna"?
8. if Quran is enough for us, then why didn't abu bakr act acording to Quran about the matter of Fadak and fabricated hadiths from Prophet (s)?
9. having a leader was so important to the companions that they left the funeral of Prophet (s) to choose their own leader, was Prophet (s) unaware of this need? (AstaghfureAllah)
10. was Allah SWT unaware of this need? (AstaghfureAllah!!!)
11. if as you claim the event in Khum didn't have anything to do with electing Imam Ali (as) as caliph, and since Islam was completed before the death of Prophet (s) then why was it left to people to choose their own leader?
12. can you bring a story from the Holy Quran where people were told to choose their own leaders? (please see 28:68 and 2:247 before answering)
13. if Prophet (s) was only trying to tell people about the behaviour of muslims towards the Ahl-ul-bait (as), then what should we say about muawia Laeen, zubair and etc who fought against Imam Ali (as)?
14. what should we say about ibn umar who was among the first ones to give baya to yazid Laeen?!
15. if Shias are not to be trusted, then why are there Shia narrators seen in the sahihayn?
16. if your sahihayn are so great, why is it that almost 50% of bukhari is only narrated by 3 people, who either fought the Ahl-ul-bait (as) or supported those who did (ayesha has narrated more than 17% of bukhari, abu hurraira and ibn umar have each narrated more than 15%)
i could continue the questions.........
.....but i think i'll just stop here
Prophet (s) didn't tell people 2 different things in 2 different places, there are no contradictions in Islam.........
and May Allah SWT save us from the lies against Him (SWT), His (SWT) Prophet (s), His (SWT), and the Ahl-ul-bait (as) of His (SWT) Prophet (s) InshaAllah........
