ABSTRACT This paper deals with the relationship between the Quran and the Sunnah. This research deals with the relationship between the Holy Qur'an and the Sunnah through a study of the hadiths in which the Prophet (peace be upon him) cited verses from the Holy Qur'an in the Sahihs of Bukhari and Muslim. The research was concerned with clarifying the concept of citation and inference to show its importance in highlighting the status of the Sunnah from the Qur'an, especially in light of the emergence of calls to be content with the Qur'an and to abandon the Sunnah. Demonstrating this complementarity is by collecting and studying fifty-five hadiths in the two Sahihs in which the Prophet (peace and blessings of Allah be upon him) cited Qur'anic verses in the chapters of belief, worship and transactions, and some separate chapters in the Shama'il, virtues and others. This reflects the depth of the Sunnah's connection to the Qur'an in various aspects of religion. It also shows that the Prophet's citation of Qur'anic verses can be of various kinds: clarification and interpretation, clarification of the general, specialisation of the general, restriction of the absolute, or adding a ruling that is not mentioned in the Qur'an. This is at the heart of the research issue; otherwise, it would not be possible to recognise the similarity between the cited verse and the prophetic hadith. The research adopted the inductive approach in extracting the hadiths from the relevant sources, their connotations and references to the wisdom contained in them, and then the analytical approach in studying the hadiths and analysing their connotations and the words of the scholars and their deductions and clarifying the connotations of these citations. The main results of the research are as follows: Providing a scientific contribution in clarifying the importance of the Sunnah and its explanatory role to the Holy Quran, responding to ideas that attempt to break the link between the Quran and the Sunnah, emphasising that both are inseparable revelations from God, refuting the claims of those who deny the Sunnah, and explaining that the Quran directs to follow what came from the Prophet (peace and blessings of Allah be upon him) is from the honourable Sunnah.
