This is a translation of a monograph titled Im‘ān fī Aqsām al-Qur’ān by Ḥamīd al-Dīn Farāhī. The author conceived it as one of the introductions to his unfinished commentary on the Holy Qur’ān, later published as Niẓām al-Qur’ān. This book discusses some issues attending the uses of oaths in the Qur’ān.
