It is almost impossible to find any single Salafi writer or speaker on Shi’ism who will not mention one ‘Abd Allah b. Saba as the founder of the Shi’i madhhab. This Ibn Saba is their bogeyman, through which they seek to scare away the truth-seekers from objectively researching the origins of Shi’ism. Expectedly, Shaykh Ibn Taymiyyah has played this same card in his infamous Minhaj al-Sunnah. He is never left behind in such matters! This book therefore is a reply to Ibn Taymiyyah first and foremost, and then to his ilk. We have compiled and critically examined all the primary Sunni and Shi’i reports about Ibn Saba. We have equally proved, through in-depth rijali investigations, that it is impossible to establish his existence in the Sunni books, to begin with. In the same manner, everything that our Sunni brothers claim about ‘Abd Allah b. Saba – especially his alleged role in the bloody overthrow of ‘Uthman, his alleged tabarra from Abu Bakr and ‘Umar, and his alleged belief in the khilafah of Imam ‘Ali – are all nothing but popular fables and notorious rumours. There is not a single reliable Sunni or Shi’i report to prove any of them. In this book, we have presented the full findings to let the world see the ignorance and dishonesty of those who peddle(d) the Ibn Saba myth as evidence.
