Name of this book is Jāmi` al-Tirmidi. it is also know as "Sunan al-Tirmidhi
It is one of the popularly Sunni Six major Hadith collections. It was collected by Abu 'Eesa Muhammad ibn 'Eesa al-Tirmidhi.
Jami At-Tirmidhi is one of the classical books of hadith that was compiled by 279AH when it's compiler and the great Muhadith, Muhammad ibn Isa ibn Surah At-Tirmidhi (209-279AH), passed away.
He was a special student of the great scholar of hadith, Imam Bukhari. He, like other great muhaditheen of our salaf, traveled a lot and quoted from many shuyukh. With 3956 ahadith, Jami' At-Tirmidi is an invaluable addition to any person's library of hadith collection.
Al-Kattani said: "The Jaami' of al-Tirmithi is also named The Sunan, contrary to those thinking them to be two separate books, and [it is also named] Al-Jaami' al-Kabeer.
Al-Hafidh Abu Al-Fadl Al-Maqdisi said: "I heard Al-Imam Abu Isma'il Abdullah bin Muhammad Al-Ansari in Harrah - when Abu Isa Al-Tirmidhi and his book was mentioned before him - saying: "To me, his book is more useful than the books of Al-Bukhari and that of Muslim. This is because only an expert can arrive at the benefit of the books of Al-Bukhari and Muslim, whereas in the case of the book of Abu Isa, every one of the people can attain its benefit."
Ibn Al-Athir said: "(It) is the best of books, having the most benefit, the best organization, with the least repetition. It contain what others do not; like mention of the different views, angles of argument, and clarifying the circumstances of the hadith as being sahih, da'if, or gharib, as well as disparaging and endorsing remarks (regarding narrators).
Of the four Sunan books, al-Tirmidhi's alone is divided into four categories. The first, those hadith definitively classified as authentic, he is in agreement with Bukhari and Muslim. The second category are those hadith which conform to the standard of the three scholars, al-Tirmidhi, al-Nasa'i and Abu Dawood, at a level less than Bukhari and Muslim. Third, are the hadith collected due to a contradiction; in this case, he clarifies its flaw. And fourth, those hadith which some fiqh specialists have acted upon.
Imam Abu Ismail `Abdullah bin Muhammad Al-Ansari in Harrah said about this book: `To me, his book is better than the book of Al-Bukhari and that of Muslim. Because only one who is an expert in knowledge can arrive at the benefit of the books of Al-Bukhari and Muslim, whereas in the case of the book of Abu `Eisa, every one of the people can reach its benefit."
Majah. These last four, known as the "Four Sunan," containing mostly Ahadith related to, and arranged according to religious regulations, have mostly been out of reach of the English reader until now.
After Sunan Abi Dawood, Imam Abu 'Eisa At-Tirmidhi's Jami` (compilation) - 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 a 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. For example, after citing the narrations of a chapter, he often explains the views of the famous A'imamah of Fiqh, like Ahmad, Ash-Shafi'i, Malik, and others. In this manner he makes clear the interpretations of these great scholars, and why they did or did not act upon this Hadith, or its like, making this collection an important Fiqh reference.
matters. His collection has the added distinguishing mark of containing many statements regarding narrators from the great scholars of Ahadith that he learned from, like Imam Ad-Darimi, whom he often cites from by saying: "I asked 'Abdullah bin 'Abdur-Rahman about this..." Of course, the most famous of these is his teacher Imam Al-Bukhari, whom he often refers to as: "I asked Muhammad" or "I heard Muhammad bin Ismai'l saying..."
Oftentimes, Imam At-Tirmidhi explains details about the name of a narrator that may be obscure in chains of narration he cited, as well as clarifying the names of Sahabah who are mentioned.
In most chapters, Imam At-Tirmidhi also explains if there are other narrations related to the topic, and from which of the Sahabah they are reported. Such topics — along with his book Al-'ilal Al-Kabir and his book Al- 'ilal As-Saghir — make his collection an important reference for the science of ilm Ar-Rijal, Ilm Ar-Riwayah and Al-Jarh wat-Ta'dil.
In summary of the benefit of Sunan At-Tirmidhi, There is none among them like the book of Abu `Eisa..And "In it are fourteen (categories) of knowledge, and that makes it easier and safer to act upon..."
By these, he indicated that this collection of Imam At-Tirmidhi includes each of these types of knowledge in it. The original text of Sunan At-Timidhi has been widely published in the Islamic world .
Lastly, all of the Ahddith in the text have been graded by the great research scholar Hafiz Zubair 'All Za'i. We ask Allah to accept our good works in this endeavor, and to cause all of the readers to attain the best benefit from it.
