Abu-Muhammad Muslih al-Din bin Abdallah Shirazi, known by his pen-name Saadi, was one of the major Persian poets of the medieval period.
Saadi is known as a mystic and metaphysician in the history of Persian literature. He is recognized for the quality of his writings and for the depth of his social and moral thoughts.
The ancient scholar has gained worldwide fame, not only in the Persian-speaking countries but in western societies, with his poems being quoted in a multitude of sources.
Saadi, who lost his father in childhood, experienced a youth of poverty and hardship; he left his hometown of Shiraz at a young age for Baghdad to pursue a better education. His first experience of education was at the Nezamiyeh University of Baghdad, where he studied Islamic sciences, theology, law, history, and Arabic literature. He traveled to different countries such as Anatolia, Syria, Egypt, and Iraq for thirty years. He also visited Qods, Mecca, and Medina.
The Master of Speech, as he is called, was a man of learning and traveling. He mingled with people from different groups from intellectuals, merchants, preachers, farmers, ordinary people to Sufi dervishes and even the thieves, trying to learn and study and also preach and advise people to gravitate to the wisdom and morality.
Returning to Shiraz as an elderly man, Saadi was greatly welcomed and respected by the ruler and the prominent figures of the city.
He spent the rest of his life in his birthplace till he passed away in around 1292.    
Saadi’s tomb is located in southern Shiraz. His mausoleum, also called Saadieh, is one of Iran’s major tourist attractions.
Many Persian elements have been used in its architecture. It is also a National Heritage Site.

Works

Saadi’s best-known masterpieces are Bustan (The Orchard) completed in 1257 and Gulistan (The Flower Garden) in 1258.

Bustan, as his best-known work, was completed in 1257. It is quite in verse, including 4,000 verses in 183 stories about the virtues such as justice, kindness, love, modesty, liberality, generosity, satisfaction and happiness, and the ecstatic practices of dervishes addressing all people to have a better and happier life.

A year after the completion of Bustan, Saadi composed his masterpiece Gulistan.

Gulistan, comprised of 8 chapters is mainly in prose. The book widely addresses kings’ morality, dervishes’ behavior, benefits of contentment, silence and talking in proper time, love and youthfulness, weakness in old age, and education.

Saadi attempts to advise people to live freely and to improve the quality of their lives in Gulistan.

It is one of the most effective books in prose in Persian literature.
