except that it is included, unless it is a commentary extracted from the ḥadīth, and this is rarely the case.

I do not know anything after the Quran that is more obligatory for people to learn than this book. It does not harm a man not to write anything from knowledge after he writes these books. And when he looks into it, reflects on it, and understands it, then he will know its importance.

As for these issues, the issues of al-Thawrī, Mālik, and al-Shāfiʿī these ḥadīths are their foundations

I like that a man writes along with these books from the opinions of the Companions of the Prophet (ṣallá Allāhu ʿalayhi wa-sallam)

And he should also write something like the collection of Sufyān al-Thawrī for it is the best of what people have compiled in collections
