عَلَيْكَ بِتِلَاوَةِ الْقُرْآنِ وَذِكْرِ اللَّهِ
“Keep to the recitation of the Qur'an and the remembrance of Allah.”
تِلَاوَة refers to reciting the Qur'an, and ذِكْر to remembering Allah. Careful recitation, growing understanding and acting upon the guidance support one another. Remembrance should also shape attention and behavior rather than remain detached from daily choices.
For example, regular recitation may remind a learner of the duty to speak truthfully, prompting them to correct dishonest behavior. The expression عَلَيْكَ بِـ functions as strong counsel to adhere to an action, not merely a literal statement about something being “upon” a person.
