Shahih Bukhari has 7275 hadith(narrations) that 4000 of it narrated by Abu Hurairah ( Cat's Father) He was a Jew before convert to Islam Quran 5:82 You will surely find the most intense of the people in animosity toward the believers [to be] the Jews and those who associate others with Allah; He convert to Islam in last 4 years of Muhammad's life but he narrated around 503000 hadith(narrations) from Muhammad. You can find 4000 narrations of Abu Hurairah in Sahih Bukhari( the most reliable book of Sunnis) but you can find 20 narrations of Imam Ali although he was the first muslim and was always beside the prophet. Imam Jafar as-Sadiq said: There was 3 persons who says lies about the messenger of Allah, Abu Hurairah, Anas ibn Malik, and a woman Sunnis say some Joks about him for example: he has good memory he was jobless so he was always beside the messenger of Allah he lived a long time after Muhammad he was the best friend of Umar, Uthman, Muawia!!!!!!!!!!!!! give me the answer and good critic about him because if you can show that he was a liar then they will be silence forever...
