خُذِ الْكِتَابَ بِقُوَّةٍ
Hold firmly to the Book.
خُذْ: an imperative verb, built on sukūn, with an implicit subject “anta.” In connected reading, “خُذِ” avoids adjacent sukūns.
الْكِتَابَ: the accusative direct object.
بِقُوَّةٍ: a prepositional expression specifying the manner of taking or holding.
The demand is not merely to touch a book but to take hold firmly and seriously. This wording occurs in Qurʾān 19:12. The imperative is supplemented by an expression clarifying how the action is to be performed.
