Jami' Al-Tirmidhi (2 Vol)

After Sunan Abi Dawood, Imam At-Tirmidhi's Jami`- better known as 'Sunan At-Timidi' is considered the most authentic among the Four Sunan. In fact, some scholars even considered Sunan At-Tirmidhi to be the best out of all of the Six Books, not based upon criteria of authenticity, but rather because of how well organized it is, making it easy for the average person to find what he is looking for, and all of the additional areas of knowledge that the author has included, which are not found in the other titles among the Six.
