ب Summary of the research: This research is submitted for a master degree in Islamic doctrine, and its title is "" The impact of the diversity of readings on matters of Islamic doctrine,"" which aims to illustrate the impact of doctrine resulting from the difference of ten frequent readings. Many motivations have stimulated me to write about this topic, most notably: 1. Infer matters of belief from the Qur'an in order to rooting the true faith in the pure souls. 2. Achieve the Qur'an greatest goal, which is understanding verses, and inferring the readings is a part of understanding the Qur'an. 3. Link between science of readings and Islamic doctrine. The research consists of an introduction and two chapters and a conclusion. The introduction talks about the reasons for choosing this topic, the previous studies, the research plan, and its methodology. The first chapter talks about science of readings and its correlation with the whole doctrine. Under this chapter there are two sections and addressed matters that benefit the subject and the title of the chapter. The second chapter contains a preface and five matters. The preface talks about other things that should be taken into consideration when talking about the correlation between doctrine and readings. The five matters are the practical applying of the verses that had different ways of reading which caused the diversity of understanding the doctrine. They have been arranged according to the six pillars of faith. The conclusion includes the results of this research, • The status of the readings in inferring the Sharia principles. • The importance of the readings and the correlation between them and the Islamic doctrine. • Method of Sunnis in inferring texts and their mediation in it.
