In The Name of Allaah, The Most Merciful, The Bestower of Mercy.
Shaikh Muqbil Bin Haadi p[rahimahullaah] said:
The Raafidah: They are those who rejected Zaid Bin Ali [rahimahullaah]. They asked him about AbuBakr and Umar [radiyallaahu-anhumaa], so he invoked Allaah’s mercy for both of them; they said, ‘Then, we have rejected you’. So, Zaid [rahimahullaah] said to them, ‘’Go, for you are rejecters.’’
Idiotic [or Ridiculous] Behaviour
Shaikhul Islaam Ibn Taymiyyah [rahimahullaah] mentioned in his tremendous book ‘Minhaajus Sunnah Vol: 1 page 13: And from the idiotic behaviour of the [Raafidah] is that they make a similitude of one they are angry with, for example they choose a female sheep that is reddish in colour because Aa’isha [radiyallaahu-anhaa] was named Al-Humayraa’u (Ref 1) [i.e. one very white in complexion]. So, they regard this female sheep to be Aa’isha [radiyallaahu-anhaa] and punish it by pulling its hair and other than that. And they consider this to be punishment for Aa’isha [radiyallaahu-anhaa].
(Ref 1)- Al-Humayraa’u: The Prophet [sallal-laahu-alayhi-wasallam] referred to Aa’isha [radiayllaahu-anhaa] as Al-Humayraa’u and this is found in a hadith narrated by Abee Salamah [radiyallaahu-anhu] and reported by An-Nasaa’ee in Sunan Al-Kub’raa’ Hadith Number:8951. Shaikh Al-Albaanee [rahimahullaah] says this Hadeeth is authentic and all its narrators are Thiqaat (trustworthy) [See: Silsilah Al-Hadeeth As-Saheehah; Hadith Number: 3277]
Hafidh Ibn Hajr says that this hadith is Saheeh. See Fathul Baaree under chapter: ‘Al-Hiraab Wad-Darq Yaumul Eed’. He also says that the other narrations containing this word ‘Al-Humaraa’u’ are weak, but only this one reported by An-Nasaa-ee [rahimahullaah] on the authority of Abee Salamah [radiyallaahu-anhu] is authentic.
Some of them [i.e. Raafidah] would name two donkeys amongst the millstone donkeys- one Abu Bakr and the other Umar; then they would punish these two donkeys and consider it to be punishment for Abu Bakr and Umar [radiyallaahu-anhumaa]. And at times they [i.e. Raafidah] write the names of Abu Bakr and Umar [radiyallaahu-anhumaa] under their feet, so one of the Muslim rulers began to beat the feet of those who did so, whilst saying, ‘’Rather, I am beating Abu Bakr and Umar’’, and he did not stop beating their [feet] until it became paralysed. Amongst them [i.e. Raafidah] is one who names his dogs AbuBakr and Umar, and then curses them. And amongst them is the one that when his dog is named Bakeer, he beats the [person] who gave it that name and says, ‘’You name my dog with the name of the inhabitants of the fire.’’And amongst them [i.e. Raafidah] are those who extol Abu LuLu’a Al-Majoosee Al-Kaafir [The fire worshipper], who was a slave of Mugheerah Bin Shubah [radiyallaahu-anhu] when he killed Umar Ibnul Khattaab [radiyallaahu-anhu]. They extol Abu LuLu’a for killing Umar, [even though] he is a disbelieving fire worshipper based on the consensus of the scholars. [Ref 1]
Some of The Zanaadiqah (Heretics) and Figureheads of The Raafidah
Al-Mu’ghee’rah Bin Sa’eed: What do the scholars say about this heretic?
Al-Haafidz Adh-Dhahabi [rahimahullaah] stated in ‘Al-Meezaan’ and Al-Haafidz Ibn Hajr [rahimahullaah] stated in ‘Lisaan Al-Meezaan’ (6/75): [He is] Al-Mughee’rah Bin Saeed Al-Bajalee Al Koofee- the Raafidi, the liar. Ibn Adee [rahimahullaah] said: ‘There was none in Kufa more cursed than Al-Mughee’rah Bin Saeed due to the falsehood he narrated about Ali [radiyallaahu-anhu]. He was always telling lies about the family of the Prophet [sallal-laahu-alayhi-wasallam] and he had no chain of narration for what he narrated.’
Al A’mash [rahimahullaah] asked the heretic Al-Mugheerah Bin Saeed, ‘’Did Ali [radiyallaahu-anhu] use to give life to the dead?’’ He replied, “By the One in whose hand my soul is, had Ali wished, he could have brought Aad and Thamud back to life.’’
The End of Al-Mughee’rah the Raafidi – the Liar
AbuBakr Bin Ayyaash [rahimahullaah] said: I saw Khaalid Bin Abdillaah Al Qasree [an Umayyad governor in Iraq] when he approached Al-Mughee’rah Bin Saeed and his followers; then he [Khaalid] killed a man amongst them and said to Mughee’rah, ‘’Bring him back to life’’, because Mugheerah used to hold that he can give life to the dead. So, Al-Mugheerah said, ‘’I swear by Allaah! I cannot give life to the dead.’’ Khaalid ordered that grass be brought to kindle a fire; then he said to Al-Mugheerah, ‘’Enter it’’, but he refused. Then a man amongst Al-Mugheerah’s companions rushed into the [fire] and burnt completely. So khaalid said to Al-Mugheerah, ‘’Wallaahi, he is worthier of leadership than you”. Thereafter, he [khaalid] killed Al-Mugheerah and his companions.
Ishaaq Bin Muhammad An-Nakha-ee Al-Ahmar: What do the scholars and Imaams of the Sunnah say about him?
Haafidh Ad-Dha’habee [rahimahullaah] stated in ‘Al-Meezaan’ and Ibn Hajr [rahimahullaah] stated in ‘Lisaanul Meezaan’ (1/370): Ishaaq Bin Muhammad An-Nakha’ee Al-Ahmar was a liar and a deviant amongst the Ghulaat (extremists).
Al-Khateeb [rahimahullaah] said: I heard Abdul Waahid Bin Ali Al-Asadee [rahimahullaah] saying: Ishaaq bin Muhammad An-Nakha’ee was upon a filthy school of thought, and he said that Ali [radiyallaahu-anhu] is Allaah [The Mighty and Majestic].
Al-Hasan Bin Yahyaa An-Nawbakh’tee (1) [rahimahullaah] stated in his book titled ‘Ar-Radd Alal Ghulaat’ [A refutation against the extremists]: Ishaaq Bin Muhammad Al-Ahmar claimed that Ali [radiyallaahu-anhu] is Allaah [Glorified be Allaah and free is He from all imperfections] and that Ali [radiyallaahu-anhu] manifested himself in Al-Hasan, and then in Al-Husain [radiyallaahu-anhumaa]; and that Ali [radiyallaahu-anhu] was the one who sent Muhammad [sallal-laahu-alayhi-wasallam] as a Messenger.
These are some of the fairy tales [or superstitions] and lies of the Raafidah and [none] can protect you from these falsehoods except Allaah [Glorified be He and free is He from all imperfections]. Therefore, you should hold fast to the Book [of Allaah] and the [authentic] Sunnah of His Messenger [sallal-laahu-alayhi-wasallam], and Allaah guides whomsoever He pleases to the straight path. And do not think that these fairy tales [or superstitions] have ceased and decreased, [rather] due to these fairy tales, the Raafidah of Iran are still waiting for the emergence of Muhammad Bin Al-Hasan Al-Askari. 
 Al-Hasan Bin Yahyaa An-Nawbakh-tee (rahimahullaah) should not be confused with Hasan ibn Musa An-Nawbakhtee who was a Shia writer.  They claim that this Hasan Al-Askari is hiding in a tunnel waiting to emerge. We’ll see the falsity of this claim Inshaa-Allaah.
The Saba’iyyoon hiding Themselves in Islaam
The Saba’iyyoon are the companions of Abdullaah Bin Saba, who said to Ali, “You are; you are”; meaning, “You are the deity”. Haafidh Adh-Dhahabi [rahimahullaah] said: Abdullaah bin Saba was from the extremists amongst the heretics- misguided and misguiding others. Ibn Asaakir [rahimahullaah] said: He [Abdullaah Bin Saba] was originally from Yemen; a Yahoodi who manifested Islaam [i.e. showed that he was a Muslim], travelled around the Muslim lands to turn them away from obedience to their leaders and to bring about evil between them, and he entered into Damascus for that reason. Abu Ya’laa [rahimahullaah] reported in his Musnad from Al-Jalaas who said, ‘’I heard Ali [radiyallaahu-anhu] saying to Abdullaah Bin Saba, ‘’Indeed, there will be thirty liars at the approach of the hour”, and you are one of them. Abdullaah bin Saba had followers and they were called the Saba’iyyoon. They believe that Godhead is with Ali [radiyallaahu-anhu]. And indeed Ali [radiyallaahu-anhu] burnt them with fire during his Khilaafah. And do not think that the followers of Abdullaah Bin Saba have perished, [rather] there is that leader of misguidance -khumeini, who displays jealousy for Islaam, yet he destroys its pillars. And some of the ignorant ones amongst the Ikhwan al- Muslimoon were deceived by Khumeini, and they used to mention him on the pulpits; but when the Book titled: ‘Jaa’a Dawrul Majoos’ came out, they were shaken. They keep quiet and did not praise Khumeini [anymore]. Perhaps the Muslims will take a lesson from the story of Abdullaah Bin Saba and be warned against the machinations [or secret plots] and filth of the Raafidah, because their call is based on deception.
