Ibn Bāz said:

❝There is no doubt that increasing Dhikr, seeking Allah’s Forgiveness, and invoking His Blessings and Peace on the Messenger of Allah 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.❞

[Fatwas of Ibn Bāz, The Book of Salah, (11/209, Part No. 11) | Alifta]
