In a situation like this, the scholars of Imamiyyah played a vital role. They had to both clarify the principles and details of the school of the Ahl al-Bayt and refuse the accusations by the opponents. They needed to discourage the weak believers of their school from showing tendency to the opposite schools; besides, they had to stop the prevalence of the opponents' ideas among the Imamiyyah Shiites. This is exactly what 'Abd al-Jalil Razi succeeded at perfectly through the book of Mathalib al-Nawasib fi Naqd Ba’d Fada’ih al-Rawafid, known as Naqd.
In order to support Imamiyyah, he presents an accurate and clear clarification about the beliefs and rules of the school of Ahl al-Bayt and determines the boundaries between Imamiyyah and Nazari Isma'iliyyah, Musta'lavid and Qarmatians; meanwhile, he does not forget to launch attacks: first, he tries to separate the lines of the "Hanafi Saljouqids" and the fatalist "Hanbalids" and "Ashab al-Hadith"; then he tries to reveal that the ideas of the naives are against the goals and intentions of the Abbasid caliphate.
