Ibn Babawayh al-Saduq, in his valuable book Kamal al-Din and in response to the doubts of the Zaydiyyah, has quoted almost the entire text of the book of Ibn Qubba, the renowned Imami theologian of Rey in the third and fourth centuries AH, who had written in response to the doubts of a Zaydi theologian named Abu Zayd Alawi regarding the issue of Imamate and specifically Imam Mahdi(a).

The name of Abu Zayd al-Alawi's book, as mentioned in Kamal al-Din, is al-Ishhad 12, and the name of Ibn Qubba's book is Naqd Kitab al-Ishhad.
Ibn Qubba has included parts of the book al-Ishhad in his refutation, and from these fragments, one can become acquainted with the views and thoughts of Abu Zayd al-Alawi, who was a Zaydi theologian and scholar in the third Hijri century.
