There are few texts translated on the notion of divine Oneness as it was envisaged by medieval Islam, which all the same seems paradoxical when we know the place that this notion occupies until this day within the Muslim community.

The text of Imam al-Juwaynî (419-478H/1028-1085), who was one of the masters of the famous al-Ghazâlî and al-Ansârî, fills this gap.

A prominent representative of the Ash'arite school, Juwayni composed the Irshâd as an implicit response to the Fatimids whose power threatened Sunni orthodoxy. It is, so to speak, the raison d'être of Kalâm (another name for Islamic theology) to answer the questions raised by authors judged, rightly or wrongly, as deviant.

The great classical themes are approached there, such as the question of divine attributes, anthropomorphism, the role of reason, etc...

As such, this work is a real sum, for those who want to get a fairly precise idea of what the elementary knowledge of any student ( tâlib ) was like at a time when the layman had no more place in the West than in the East.
