Nahj al-balāgha (the Peak of Eloquence) is a collection of sayings and writings of Imam 'Ali (a) which have been compiled by al-Sayyid al-Radi in late 4th/10th century (finished in 400/1009-1010).

Nahj al-balagha has been organized into three parts: sermons, letters and short sayings. Throughout the sermons, dealing with a wide variety of topics including our existence, relationship with the Almighty, building a God-fearing personality, and the Imam's (a) reflections upon historical incidents, Imam (a) calls people to obey God's orders and abandon prohibitions and in his letters advises his agents to observe the rights of people. Kalimat al-qisar (short sayings) of Nahj al-balagha are a collection of wise sayings stated at the Peak of Eloquence.
