You missed the entire point, I agree with most of your post, let me comment quickly:
There are many things we Muslims do as identification of our religion which have become our symbols which actually originate in Iran, especially our dress, some of the terminology we use "Durood" "Panjtan Paak" "Chaasht" "Roza Daari" etc. I have even seen Arabs using these terms. Plus our tradition was developed by mostly Iranian figures. Imams Bukhari, Muslim Nishapuri, Tirmizi, Ibn Maja Qazvini, Abu Dawud Sijistani, Nasai. Our culture, cuisine, architecture, etc.
First of all influence of language can't be compared to a mythical dagger that that symbolises Majoosi Majoosi grudge and found its way in Sunni circles. The influence of language is not problematic per se, a symbolic Majoosi dagger upholded by closet-Majoos (Rafidah) more than anybody else is not a good thing.
Your logic is flawed, so just because the influence of Persian language (it was huge since ironically non-Persian Turkic tribes and Mongols spread it in Asia) and let's say clothes and even food (Biryani is Persian in origin but not known in modern day Iran at all) has influenced the Islamic world, we must accept everything Persian too? Many hardcore nationalistic Persians (who are united with the Shia on this and many other matters) also revere Abu Lu'lu'ah (I've posted the article), shall we revere him too? We should take the good of any culture and leave the bad, this is a middle path, the Majoosi dagger is a myth and THE main symbol of the modern day closet-Majoos, so we must purify our heritage from it.
Besides, not all the Imams of you mentioned are Persian, being born in Persia doesn't make you ethnic Persian, back in those days numerous Arab tribes settled in Persia. I myself am of Persian-Arab backround and have no bias against any of them.
The Hadith of Salman al Farisi when Sura al-Jumuah was revealed, and the Prophet Sallallahu alaihi wasallam said placing his hands on Salmaan that if faith were to be suspended at the Pleiades a man or men from the people of Salmaan al Faarisi would be raised to reach it.
Yes, a famous Sunni hadith that Shias misuse to praise post-Safavid Iran, although it can't be found in their own books with an authentic chain, it's a Sunni hadith about the great Muslim people, the Ahl Al-Sunnah of Persia, I wrote an article about that:
https://sonsofsunnah.com/2014/09/10/a-pro-persian-sunni-hadith-that-is-misused-by-the-rafidah-shia/So after the Arabs, the natural leaders of the Muslim world even till this day are the Iranians. And I don't just mean Iran, because the Kurds, Baluch, Tajiks, Afghans are all Iranian peoples too.
I agree with you.
The people whom the Prophet Sallallahu alaihi wasallam warned about were the Turkic peoples,
Yes, but he referred to the actual Turks, Anatolian Turks, most of them are natives to Anatolia and share the same DNA of the people of that region, they are mostly Turkified. Modern studies state that overall, modern Turks are most related to neighbouring West Asian populations. A study looking into allele frequencies suggested that there was a lack of genetic relationship between contemporary Mongols and Turks, despite their linguistic and cultural relationship. In addition, another study looking into HLA genes allele distributions indicated that Anatolians did not significantly differ from other Mediterranean populations. Therefore the Turks are most likely the Mongolians, the people of Genghis khan (Abu Allayari).
and certain Bedouin tribes like Bani Tamim.
We have to be fair, the first Khariji was a Tamimi, however, as a matter of fact the Prophet (saws) HUGELY praised this tribe (to this day the vast majority of them are staunch Sunnis, Muhammad Ibn Abdil-Wahhab was Tamimi too):
Narrated Abu Huraira:
I have loved the people of the tribe of Bani tamim ever since I heard, three things, Allah's Apostle said about them. I heard him saying,
These people (of the tribe of Bani tamim) would stand firm against Ad-dajjal."
When the Sadaqat (gifts of charity) from that tribe came, Allah's Apostle said,
"These are the Sadaqat (i.e. charitable gifts) of our folk."
'Aisha had a slave-girl from that tribe, and the Prophet said to 'Aisha, "Manumit her as she is a descendant of Ishmael (the Prophet)."
(Sahih Al Bukhari. Book #46, Hadith #719)
Narrated Abu Huraira: I have not ceased to like Banu tamim ever since I heard of three qualities attributed to them by Allah's Apostle (He said): They, out of all my followers, will be the strongest opponent of Ad-dajjal; 'Aisha had a slave-girl from them, and the Prophet told her to manumit her as she was from the descendants of (the Prophet) Ishmael; and, when their Zakat was brought, the Prophet said, "This is the Zakat of my people."
(Book #59, Hadith #652)
Abu Huraira reported: Since I heard three things from Allah's Messenger (may peace be upon him) my love for Banu tamim is never on the decline (and these things are): I heard Allah's Messenger (may peace be upon him) as saying about them that they would put up stout resistance against Dajjal amongst my Umma. And he (the narrator) said: (When) the consignment of Zakat was brought to him, Allah's Messenger (may peace be upon him) said: This is the charity of our people, and there was one slave-girl in the house of 'A'isha and she was from the tribe of Banu tamim; thereupon Allah's Messenger (may peace be upon him) said: Set her free, for she is from the offspring of Isma'il. The other hadith has been transmitted on the authority of Abu Huraira with a slight variation of wording.
(Sahih Al-Muslim. Book #031, Hadith #6133)
Abu Huraira reported: There are some distinguishing features of Banu tamim which I heard from Allah's Messenger (may peace be upon him) and my love for them is never on the decline after that and the words are: They are the bravest amongst people in the battlefield and there is no mention of (the word)" Dajjal".
(Sahih Al-Muslim. Book #031, Hadith #6134)
