Shiaism (The Rafidah) and Islam are indeed different religions. This sect has developed into what we now know as the Shia whose beliefs and thoughts are repugnant beyond belief. The divergence of Shiaism from Islaam can be summarized from the books which they consider most authentic, and the statements of their most respected scholars. Some of the proofs are available on this page Most of the Muslim UMMAH and Western scholars have very little genuine and reliable knowledge of SHIA beliefs and practices. However, most of the openly declared SHIA beliefs revolve around The Concept of Imamah , the superiority of Ali (May Allah be pleased with him), and the so-called love of the Prophet's family members. As a result, the intense love that Sunni Muslims carry for the Prophet's family members combined with the magnanimous personality of Ali has led some Sunnis to accept Shia's as part of the Muslim UMMAH.
However, the brutal fact remains that under the pretense of Ali's Superiority and the so-called love of the Prophet's family members, Shias have literally evolved an entirely new religion, grossly distorted the teachings of the Holy Qur'ân, and completely rejected the sanctity and authenticity of the Hadeeth. They have elevated the sayings of their imams to the level of the Prophet's sayings and have classified them as Hadeeth. For all practical purposes, they reject the most authentic sayings of the Prophet (Peace be upon him) and Base their religion on the so-called Hadeeth attributed to their Imaams. By doing so they have rejected one of the most fundamental principles of Islam: The law can only be derived from the sayings and actions of the Prophet (Peace be upon him), not any other human being.
The Saba'iyyah , a sect of the Rawafid, emerged in the time of `Ali and told `Ali he was God. `Ali (may Allah be pleased with him) burned some of them to death as a result. Later, the Rawafid split into many groups like: The Zaydis, Imamis, Kaysaniyyas, Qaddahiyyas and Exaggerators (Ghullat). Some people asked Imam Zayd ibn `Ali to disavow Abu Bakr and `Umar. He would not do so, and some people refused his decision, and deserted him, thereby becoming known as Rawafid, which means : the Refusers, the Rejecters. Those who stayed with him became known as the Zaydis, and so they are technically not of the Rawafid. The exaggerators are not Muslims, these Raafidi (Shia) actually descend from Abu Lu'luah Majoosi (a Persian fire worshipper) and Abdullaah ibn Saba' (a Jew). However they are more dangerous from the Christians themselves. Christians fight Islaam face to face (if they did) while Rafidiyah stab Islam from its back they have lot of Absurdities in their beliefs like Badah, Rajah, Mutah, Taqiyyah, etc
The Zaydis, Imamis and exaggerators split up further, with each group accusing the other of kufr. The Zaydis split into three groups: Jarudis, Sulaymanis and Butris. They all agreed on the leadership of Imam Zayd ibn `Ali ibn al-Husayn when he revolted at the time of Hisham ibn `Abdul-Malik. They are the closest of the Shiah to Ahlus-Sunnah; they merely maintain that `Ali had more right to the Caliphate, but they do not claim that he was explicitly appointed as Caliph by the Prophet (may Allah bless him and his Household and grant them peace), and hence they accept the Caliphates of Abu Bakr, `Umar and `Uthman. The Kisanis split into two groups: one claimed that Muhammad ibn Hanafiyyah, a son of `Ali, is still alive and that he is the Mahdi; the other group say he died and passed on the leadership.
The Imamis and exaggerators split into fifteen groups, among which are the Ja`faris/Ithna `Asharis (Twelvers) and the Isma`ilis. The exaggerators claimed divinity for their Imams, permitted all sorts of haram things, and in short dismissed the obligations of shari`ah.
Below we have more then 100 Articles exposing Shia's using their own books and writings with detailed sources so that they don't deny it. These references are copied from the religious books of Shiite religion. While translating them we have asked forgiveness of Allah many times, for, these are very much annoying for any Muslim to read. Neither I personally wish anyone to have them but to save the innocent simple Muslims from the Shiites (Raafidah) it was necessary to write them and forward them to our fellow Muslims so that they can know the real terrifying beliefs of Shiites. Additionally I have also listed some articles about Ismailism and the Agakhanis; one of the more deviant groups within the Shia religion they are an offshoot of the Raafidah (Shiah) and share some of their characteristics. Aga Khan is their supreme leader and, in their view, has characteristics and attributes similar to those of Allaah.
And Lastly The Prophet said: "Whoever abuses my Companions, upon them is the curse of Allah, the Angles and all the people" (Saheeh, At-Tabaranee)
