What is the scriptural definition of Bulugh al-Maram and Zad al-Mustaqni' in terms of content and madhhab, and which of them is better, and are they sufficient for a Muslim, or is it necessary to read fiqh in other books alongside them, and what is the authenticity of the hadiths in each of them, and which of them has more authentic hadiths?

It is not possible to compare "Zad al-Mustaqni'" and "Bulugh al-Maram" due to their differing subjects. "Zad al-Mustaqni'" is a concise jurisprudential text based on the school of Imam Ahmad, mentioning legal issues without excessive elaboration on sub-branches or mentioning evidence. It is important for students of the Hanbali school, along with its commentaries such as "Al-Rawd al-Murabbi'" and "Al-Sharh al-Mumti'." As for "Bulugh al-Maram," it is a meticulously compiled hadith text by Al-Hafiz Ibn Hajar Al-Asqalani, in which he gathered the hadiths of rulings, along with his judgments on these hadiths. It holds great fame for being one of the most important books of hadiths related to rulings. The two books complement each other; one mentions jurisprudential issues, and the other mentions the evidence for rulings. It is recommended to diligently seek knowledge from reputable scholars and to read the works of contemporary scholars.
