Three protections at morning and evening
مَنْ قَالَ حِينَ يُمْسِي ثَلَاثَ مَرَّاتٍ: أَعُوذُ بِكَلِمَاتِ اللَّهِ التَّامَّاتِ مِنْ شَرِّ مَا خَلَقَ، لَمْ تَضُرَّهُ حُمَةٌ تِلْكَ اللَّيْلَةَ
Man qala hina yumsi thalatha marrat: A'udhu bi-kalimati-llahi-t-tammati min sharri ma khalaq, lam tadurrahu humatun tilka-l-laylah.
"Whoever says three times in the evening: I seek refuge in the perfect words of Allah from the evil of what He created, no harm shall touch him that night."
Narrated by Abu Hurayrah. Sunan at-Tirmidhi 3604
A short reflection
A sentence said three times each evening, a sentence said three times each morning. Total time: under a minute. Promise: protection of the night and the day.
