Imam Bukhari declared: I dont see any difference between praying Salah behind a Jahmi or a (Shia) Rafidhi and a Christian or a Jew. They (Jahmis/Rafidhis) are not to be greeted, nor are they to be visited, nor are they to be married, nor is their testimony to be accepted, nor are their sacrifices to be eaten. (Khalq Afaalul-Ibaad, p.14) ---------------------------------------------- Imaam Abu Hanifah
It was reported that often Abu Haneefah used to repeat the following statement about the Shi`ites, "Whoever doubts whether they are disbelievers has himself committed disbelief."

Imaam al-Shaafi`e
On one occasion al-Shaafi`i said concerning the Shi`ites, "I have not seen among the heretics a people more famous for falsehood than the Raafidite Shi`ites." [Ibn Taymeeyah, Minhaaj as-Sunnah an-Nabawiyyah, 1/39] On another occasion he said, "Narrate knowledge from everyone you meet except the Raafidite Shi`ites, because they invent Hadeeths and adopt them as part of their religion." [Ibid, p. 38]

Imaam Maalik
Once Maalik was asked about them and he replied, "Do not speak to them nor narrate from them, for surely they are liars." [Minhaaj as-Sunnah, 1/37] During a class of Imaam Maalik, it was mentioned that the Raafidite Shi`ites curse the Sahaabah. In reply, he quoted the Quranic verse, "Muhammad is the Messenger of Allah and those with him are harsh with the disbelievers and gentle among themselves. So that the disbelievers may become enraged with them." He then said, "Whoever becomes enraged when the Sahaabah are mentioned is one about whom the verse speaks." [Tafseeer al-Qurtubee, Soorah al-Fath; Editors note: That is, anyone who is enraged by the mention of the Sahaabah is a dsibeliever, because the verse says, "the disbelievers may become enraged with them (Sahaabah)."]
