Narated By Wathilah ibn al-Asqa' : The Apostle of Allah (pbuh) led us in prayer over bier of a Muslim and I heard him say: O Allah, so and so, son of so and so, is in Thy protection, so guard him from the trial in the grave. (AbdurRahman in his version said: "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 worthy of praise. O Allah, forgive him and show him mercy. Thou art the forgiving and the merciful one." AbdurRahman said: "On the authority of Marwan ibn Janah."
