Ibn Bāz (رحمه الله تعالى) said:

❝There is no doubt that increasing Dhikr, seeking Allah’s Forgiveness, and invoking His Blessings and Peace on the Messenger
of Allah (صلى الله عليه وسلم) are of the greatest ways of calming hearts and bringing rest and tranquility to them, having faith in Allah, and removing loneliness, vacillation, and confusion.❞
