Aban ibn Uthman Radi Allahu Anhu said

✦ Aban ibn Uthman Radi Allahu Anhu said: I heard Uthman ibn Affan Radi Allahu Anhu (his father) say: I heard the Messenger of Allah Sallallahu Alaihi Wasallam said: If anyone says three times (in the evening) :

بِسْمِ اللَّهِ الَّذِي لَا يَضُرُّ مَعَ اسْمِهِ شَيْءٌ فِي الْأَرْضِ وَلَا فِي السَّمَاءِ وَهُوَ السَّمِيعُ الْعَلِيمُ

Bismillahillazi La yadurru Maasmihi Shaiun fil-ardi wa La fis-smaaie, Wahuwas Samiul Alim.

he will not suffer sudden affliction till the morning, and if anyone says this in the morning, he will not suffer sudden affliction till the evening.

Aban Radi Allahu Anhu was afflicted by some paralysis and when a man who heard the tradition began to look at him, he said to him: Why are you looking at me? I swear by Allah, I did not tell a lie about Uthman, nor did Uthman tell a lie about the Prophet Sallallahu Alaihi Wasallam , but that day when I was afflicted by it, I became angry and forgot to say them.

(Dua Translation: In the name of Allah, when Whose name is mentioned nothing on Earth or in Heaven can cause harm, and He is the Hearer, the Knower")
