Sunan Abu Dawud is one of the great collection of ahadith after Sahih Bukhar & Sahih Muslim. It was compiled by Imam Abu Dawud. From amongts Fifty Thousand collected hadith, Imam Abu Dawud just only included 4800 hadith in his book. Imam Abu dawud took almost 20 years to collect this ahadith. We have to know that Sunan Abu Dawud contain Sahih, Weak i.e Daeef and Fabricated. So we have to be careful in this subject at the time of collecting hadith from Sunan Abu Dawud. May Allah save Imam Abu Dawud from Jahannam and Grant Jannat for his Great contribution in the field of Islam.
