Muslim b. Ḥārith al-Tamīmī (raḍiy Allāhu ‘anhu) narrates that the Messenger of Allah ﷺ secretly said to him: “When you finish Maghrib, say [the above] seven times. If you say that and then die during that night, it will be a protection for you. And after praying Fajr, say the same. If you die on that day, it will be a protection for you.” (Abū Dāwūd 5079)
