The Book Pertaining to Repentance and Exhortation to Repentance (Kitab Al-Tauba)
Muslim :: Book 37 : Hadith 6640
Abu Sa'id Khudri reported that Allah's Messenger (may peace be upon him) said that a person amongst the earlier nations before you was conferred property and children by Allah, He said to his children: 'You must do as I command you to do, otherwise I will make others besides you as my inheritors. As I die, burn my body and blow my ashes in the wind as I do not find any merit of mine which would please Allah, and if Allah were to take hold of me, He would punish me. He took a pledge from them and they did as he commanded thein to do. Allah said: What prompted you to do this? He said: My Lord. Thine fear, and Allah did not punish him at all.
