Risalat al-Huquq (Arabic: رسالة الحقوق, lit. 'treatise of rights') is an early Islamic text about social and religious responsibilities. The book is attributed to Ali al-Sajjad (d. c. 712 CE), an imam in Shia Islam, and the great-grandson of the Islamic prophet, Muhammad. Risalat al-Huquq exhaustively describes the rights God has upon humans and the rights humans have upon themselves and on each other, as perceived in Islam. Risalat al-Huquq has been related by Abu Hamza al-Thumali, a close confidante of al-Sajjad. Source: Wikipedia (en)
