'Auf bin Malik (RAA) narrated that the Messenger of Allah (ﷺ) offered the funeral prayer, and I memorized this supplication (that he said for the deceased), "'O Allah! Forgive him and have mercy on him (on her). Grant him ease and respite. Make his resting place a noble one, and facilitate his entry. Wash him with the most pure and clean water, snow and hail. Purify him from sins as a white garment is cleansed of dirt. Give him in exchange a home better than his home (on earth) and a family better than his family. Grant him entrance to Paradise and protect him from the trials of the grave and the torture of Hell Fire." Related by Muslim.
