increase religious commitment

{ The believers are only those who, when Allāh is mentioned, their hearts become fearful, and when His verses are recited to them, it increases them in faith; and upon their Lord they rely }

{ And whenever a sūrah is revealed, there are among them [i.e., the hypocrites] those who say, "Which of you has this increased in faith?" As for those who believed, it has increased them in faith, while they are rejoicing. }
