TRIAL OF THE GRAVE H 952 "The Prophet, praise and peace be upon him, led us in a funeral prayer for a deceased Muslim. I (Wathilah) heard him supplicate, 'O Allah, so and so, son of so and so is under Your covenant and secure in Your nearness. Shield him from the trial of the grave and the punishment of Hell. You are the Owner of Fulfillment and Praise. O Allah, forgive him and have mercy on him. Indeed You are the Most Forgiving, the Most Merciful.'" R 952 Abu Daud with a chain up to Wathilah son of Aska'a who related that the Messenger of Allah, praise and peace be upon him, said this.
939- وعن وَاثِلَة بنِ الأَسْقَعِ رضي الله عنه ، قَالَ : صَلَّى بِنَا رسول الله صلى الله عليه وآله وسلم عَلَى رَجُلٍ مِنَ المُسْلِمِينَ ، فَسَمِعْتُهُ يَقُولُ : "اللَّهُمَّ إنَّ فُلانَ ابْنَ فُلانٍ في ذِمَتِّكَ وَحَبْلِ جِوَارِكَ ، فَقِهِ فِتْنَةَ القَبْرِ ، وَعذَابَ النَّار ، وَأنْتَ أهْلُ الوَفَاءِ وَالحَمْدِ ؛ اللَّهُمَّ فَاغْفِرْ لَهُ وَارْحَمْهُ ، إنَّكَ أنْتَ الغَفُورُ الرَّحيمُ" رواه أَبُو داود .
