Shaikh Sadi ( 1184- 1283)  Lived through the golden age of Islam but also witnessed the death and destruction inflicted by the Mongol invasion in the entire region east of Egypt. In Baghdad alone in 1258 close to a million people were killed in a city of less than 2 million. Institutions of higher learning masques were destroyed. Khaliq

Here is a quote from his Bostan.


Thou, O creature of G-d, wast created of the dust; therefore, be humble as the dust. Be not covetous, nor oppressive, nor headstrong. Thou art from the dust; be not like fire. When the terrible fire raised his head in pride, the dust prostrated itself in humility.
