Takhrij Hadith 1381: "Whoever says in the morning…"

Whoever says in the morning or evening: “O Allah, I have entered the morning [or evening] calling You to witness, and I call the bearers of Your Throne, Your angels, and all of Your creation to witness, that You are Allah; there is no god but You; and that Muhammad is Your servant and Messenger”—Allah will free one-quarter of him from the Fire. Whoever says it twice, Allah will free half of him; whoever says it three times, Allah will free three-quarters of him; and if he says it four times, Allah will free him completely from the Fire.
