There exists a phenomenon of some Muslims who study hadith but do not emphasize the study of fiqh using a madhhab. Although I may still hold some individuals who do this in high regard, I no longer view their understanding of the enterprise of hadith authoritative in comprehensive terms unless they respect and understand hadith through their usage in the madhhabs of fiqh as well. Of course, they may still have a remarkably high level of taqwa, write important works or be valuable scholars in some capacity, but they are missing a few components that would carry them to a higher level of knowledge and understanding of the Sunnah.
"Anyone who has a brain should nourish his intellect just as he nourishes his stomach and there is no better way to nourish the mind than reading a book and benefiting from it. Read whatever you can get your hands on, even if it's a cookbook."
A student of knowledge can forget anything, but should never forget sending salutations upon the Prophet ﷺ whenever and wherever his name is read or mentioned.
