5. `Ali ibn `Abd Allah al-Warraq said: Muhammad ibn Ja`far ibn Buttah said: Muhammad ibn al-Hasan al-Saffar, Muhammad ibn `Ali ibn Mahbub and Muhammad ibn al-Husayn ibn `Abd al-`Aziz all three said, on the authority of Ahmad ibn Muhammad ibn `Isa, on the authority of al-Husayn ibn Sa`id, on the authority of Hammad ibn `Isa al-Juhani, on the authority of Hariz ibn `Abd Allah that Abu `Abd Allah al-Sadiq said: Verily, on the subject of free will, there are three types of persons. One person claims that Allah, the Mighty and High, has compelled people to sin. He is an unbeliever who has insulted the judgment of Allah. The second person claims that Allah has relinquished all mattes. He is an unbeliever as well, as he has insulted the rule of Allah. The third person claims that Allah only obliges His Servants to do what they have the strength to do, and does not oblige them to do what they do not have the strength to do. This is the correct Muslim: he who praises Allah when he does good and repents to Allah when he commits a sin.
