Mishkat al-Masabih #1592

Wathila b. al-Asqa‘ said God’s messenger led them in prayer over a Muslim and he heard him say, “O God, so and so son of so and so is in Thy protection and in Thy nearer presence, so guard him from the trial in the grave and the punishment in hell. Thou art faithful and true. O God, forgive him and show him mercy. Thou art the forgiving and the merciful One.” Abu Dawud and Ibn Majah transmitted it.
