What is the optimal methodology for authoring a book on "The Forty Hadiths on Seeking Knowledge" to ensure its scientific rigor?

The primary purpose of compiling "Forty Hadith" collections is to disseminate the Sunnah, thereby attaining the virtue mentioned in the Hadith of Zayd ibn Thabit: «May Allah brighten the face of a person who hears a Hadith from us, memorizes it, and conveys it to others.» This Hadith was authenticated by Al-Albani. As for specifying the number "forty," its reason is a weak Hadith, but scholars have agreed on the permissibility of acting upon it regarding virtuous deeds. Imam Al-Nawawi also clarified that his reliance in his compilation was not on the weak Hadith, but rather on authentic Hadith such as: «Let the one who is present convey it to the one who is absent.»

Scholars differed in their methodology for compiling the Forty Hadith. Each compiler set a specific condition and methodology for themselves. Some are musnad (with full chains of narration), some have omitted the asanid (chains of narration), some are specific to a particular topic, and some are general. Imam Al-Nawawi collected forty Hadith that are considered great foundations of the religion, and he committed to ensuring they were authentic and that their asanid were omitted to facilitate memorization. In conclusion, there is no condition that must be adhered to when compiling forty Hadith on a specific topic, except for the condition of the authenticity of the Hadith, and thereupon, the compiler must adhere to the purpose he set for his compilation.
