Bismillahi-lladhi la yadurru ma'asmihi shay'
مَنْ قَالَ ثَلَاثَ مَرَّاتٍ: بِسْمِ اللَّهِ الَّذِي لَا يَضُرُّ مَعَ اسْمِهِ شَيْءٌ فِي الْأَرْضِ وَلَا فِي السَّمَاءِ، وَهُوَ السَّمِيعُ الْعَلِيمُ، لَمْ يَضُرَّهُ شَيْءٌ
Man qala thalatha marrat: Bismi-llahi-lladhi la yadurru ma'asmihi shay'un fi-l-ardi wa la fi-s-sama', wa huwa-s-sami'u-l-aleem, lam yadurrahu shay'.
"Whoever says three times: In the name of Allah, with whose name nothing in the earth or the sky can harm, and He is the All-Hearing, the All-Knowing, nothing will harm him."
Narrated by Uthman ibn Affan. Sunan Abi Dawud 5088, Sunan at-Tirmidhi 3388
A short reflection
Three times in the morning, three times in the evening. The verbal seal of Bismillah, layered.
