In this newly translated book by Sheikh Karimi, Shawahid al Tanzil was originally compiled by a great Sunni scholar of the 5th century which looks at verses of the Qur'an revealed in honour of the Ahlulbayt (AS).
Shawahid al-Tanzil li Qawa'id al-Tafdil written by al-Hakim al-Haskani (d. 490 AH) is one of the most comprehensive books written on this subject. In this book, which is in the order of the Surahs of the Quran, more than 200 verses have been mentioned in connection with the merits of Imam Ali, and after each verse, one or more narrations from the eminent companions of the Prophet SAW have been quoted. The total number of narrations is 1160.
Al-Hakim al-Haskani is one of the most prominent Sunni scholars in the fifth century AF and was proficient in hadith and rijal, as confirmed by al-Dhahabi among others. As the author explains in the introduction, his motivation for writing this book was the baseless claim that no verse in the Quran was revealed about Imam Ali. So he proceeded to compile this book, in which he has quoted all the verses reveled about the Ahlul Bayt in general and Imam Ali in particular, or interpreted as being in reference to them.
Due to the prominence of the author and his special mastery in hadith studies, and also due to the fact that this book is one of the most important early texts, Shawahid al-Tanzil li Qawa'id al-Tafdil is one of the most important sources for both the Shi'a and Sunnis to know Imam Ali and the Ahlul Bayt.
