مسند أحمد

It was narrated from Aban bin `Uthman, from `Uthman, that The Prophet (ﷺ) said: `Whoever says, `In the Name of Allah with Whose name nothing on earth or in heaven can cause harm, and he is the All-Hearing, All-Knowing.` three times, will not be struck unawares by calamity until night comes, and whoever says it in the evening will not be struck unawares by calamity until morning comes, in sha` Allah.”
