Imam Abu Dawud Sulaiman ibn Ash`ath ibn Ishaq ibn Bashir ibn Shaddad ibn `Umar ibn `Imran al-Azdi Sajastani.

Imam Abu Dawud was born in Sajistan, a famous city in Khurasan in the year 202 A.H. He belonged to the Arab tribe, Azd. Even though he was born in Sajistan he spent the greater part of his life at Basrah which was the seat of Islamic learning in his time. Imam Abu Dawud also travelled for collecting hadith. Many times he visited Bagdad. He also went to Hijaz, Egypt, al-Jazirah, Nishapur, Syria and Isfahan.

He was blessed with an exceptional mind.Only four persons are reported to have earned their names for the criticism of hadith. They are: Imam Bukhari, Imam Muslim, Imam Abu Dawud and Imam Nasa'i. Imam Abu Dawud lived during the time when the Muslim world was full of eminent scholars. He had so much command over hadith, he was considered by many as Imam al-muhaddithin of his time.

He was a religious man. He led a pious and ascetic life. He devoted most of his time for worship, devotion and remembrance of Allah. He always kept away from men of rank, the company of sultans and courtiers.

Imam Abu Dawud heard hadith from 300 persons who were his teachers. Some were: Imam Ahmad ibn Hanbal, Ishaq ibn Rahawaiy, Abu Thaur, Yahya ibn Ma'in. For one to grasp his elevated status, he narrated hadith to the teachers of Imam Ahmad. Imam Ahmad ibn Hanbal also narrated one hadith from him. Among the students of Imam Abu Dawud are great personalities like:
Ibn Arabi, Abu `Isa al-Tirmidhi and Abu `Abdur-Rahman An Nasa'i.

They were transmitters of his famous work Sunan Abu Dawud. Imam Muslim was also one of his pupils. Imam Abu Dawud's works are:

1-Kitab Al Radd Ala' Ahl al Qadar 2-Kitab Al Masa'il

3-Musnad Malik 4-Kitab Al Marasil 5-Sunan Abu Dawud.

His most famous of all his works is Sunan Abu Dawud. It contains 4800 traditions which were taken out from a collection of 500,000 hadith.

He completed its compilation at Bagdad in 241 A.H. He presented the completed compilation to his beloved teacher Imam Ahmad ibn Hanbal who was greatly pleased at this collection.

Sunan Abu Dawud is an important collection of hadith: Most of the scholars have assigned it to third position among the six authentic books of hadith. It is only after the compilation of Sahih Bukhari and Sahih Muslim.

A few statements from scholars of hadith concerning Sunan Abu Dawud:

Ibn al-Jawzi said:

Abu Dawud was an eminent doctor of hadith and an outstanding scholar. No one has compiled a book like his Sunan.

Ibn Kathir remarked:

Sunan Abu Dawud is considered to be a famous and popular work among scholars.

Imam Abu Dawud himself has stated:

From this book of mine four (4) hadith are sufficient for an intelligent and insightful person. They are:

Deeds are to be judged only by intentions.
Part of a man's good observance of Islam is that he leaves alone that which does not concern him.
None of you can be a believer unless you love for your brother that which you love for yourself.
The permitted (halal) is clear, and the forbidden (haram) is clear, between these two are doubtful matters. Whosoever abstains from these doubtful matters has saved his religion.

The traditions compiled in Sunan Abu Dawud were generally followed by companions, successors and their followers. It is a basic source of knowledge about the legal points of views held by Imam Malik, Sufyan Al-Thawri and Al-Awza'i. It serves as an arbiter for disagreement among jurists.

Imam Abu Dawud died on Friday 16th Shawwal 275 A.H.
