The Prophet (ﷺ) supplicated in course of funeral prayer: "Allahumma Anta Rabbuha, wa Anta khalaqtaha, wa Anta hadaytaha lil-Islam, wa Anta qabadta ruhaha, wa Anta a'lamu bisirriha wa 'alaniyyatiha, ji'naka shufa'a'a lahu

[if the dead person is a man, or laha if the dead person is a woman], faghfir lahu

[or laha, if it is a woman] (O Allah, You are its Rubb; You created it; You guided it to Islam; You have taken its life back and You know best its insight and outer condition. We have come as intercessors, so forgive him)."

[Abu Dawud].
