Explanation of the author's statement: "And perhaps I have omitted from it rare issues and added what is relied upon in similar cases"

The Shaykh :"And perhaps I have omitted from it rare issues" Perhaps I have omitted from al-Muqni' some issues; "issues" is the plural of "issue," and an issue is that for which evidence is sought in knowledge, meaning that for which proof is established in knowledge and religion, and for which evidence is sought, and it is called an issue. For this reason, they said, "Knowledge consists of issues and evidence". The evidence is either auditory or rational. If it is based on a text from the Book or the Sunnah or consensus, it is auditory; if it is based on analogical reasoning, it is rational. Thus, all knowledge, including the principles of religion and beliefs, consists of issues and evidence. Issues establish rulings, and evidence establishes these issues. We said that the evidence is auditory and rational. The auditory evidence is the Book, the Sunnah, and consensus, and the rational evidence is analogical reasoning and what reflection necessitates. Now, "rare issues" means issues that are infrequently encountered, because rare issues are those with which a person should not occupy himself. For example, those who occupy themselves with riddle-like issues; many people have a passion for very rare issues that may never occur, such as riddle-like issues, because, as the common people say, "Oppose, and you will be remembered". But there is no reason to write down rare issues. If rare issues occur, may Allah make their solution easy. However, frequently occurring issues are the important ones. For this reason, the author said, frequently occurring. "And I added what is relied upon in similar cases" I added what is relied upon in similar cases. "What" here is a relative pronoun meaning "that which," and its relative clause is "is relied upon." "In similar cases" is attached to "is relied upon," meaning I added what is relied upon in similar cases. However, the word order was inverted for the sake of harmony, the harmony of rhyming. "And I added what is relied upon in similar cases" means I added important issues that are relied upon. Thus, the composition of this book, in relation to al-Muqni', consists of three things. First, it is a summary based on a single opinion.
