Takhrij Hadith 1683: "Whoever says after every prayer…"

Whoever says after every prayer and when he goes to bed: Allah is the Greatest, immensely great, as many times as all that is even and odd, and as many times as the perfect, good, blessed words of Allah—three times—and says: There is no deity worthy of worship except Allah, in the same manner—three times—these words will be a light for him in his grave, a light for him upon the Bridge, and a light for him upon the Sirat (the bridge laid over Hell), until they admit him into Paradise—or until he enters Paradise.
