Narrated By Abu Huraira: I have memorized two kinds of knowledge from Allah's Apostle . I have propagated one of them to you and if I propagated the second, then my pharynx (throat) would be cut (i.e. killed). [Sahih Bukhari, Vol 1, Book 3, Hadith #121]
What is the interpretation of this hadith from the scholars, why would Abu Huraira get his throat cut for with holding knowledge that was taught to him by Prophet Muhammad (s)?!
