ابن قيم الجوزية
İbn Kayyim el-Cevziyye

Muhammad ibn Abi Bakr (also known as Ibn Qayyim ("The son of the principal") or Ibn Qayyim al-Jawziyyah ("Son of the principal of the (school of) Jawziyyah")) (1292-1350CE / 691 AH- 751 AH) was a Sunni Islamic jurist, commentator on the Qur'an, astronomer, chemist, philosopher, psychologist, scientist and theologian.

Although he is sometimes referred to as "the scholar of the heart," given his extensive works pertaining to human behavior and ethics, Ibn Qayyim's scholarship was focused on the sciences of Hadith and Fiqh.
