Sunan Ibn Majah, Chapter: The Chapters of Establishing the Prayer and the Sunnah Regarding Them

"The Messenger of Allah (saw) said: 'The best of your days is Friday. On it Adam was created, on it the Trumpet will be blown, on it all creatures will swoon. So send a great deal of peace and blessings upon me on that day, for your peace and blessings will be presented to me.' A man said: 'O Messenger of Allah, how will our peace and blessings be shown to you when you will have disintegrated?' He said: 'Allah has forbidden the earth to consume the bodies of the Prophets.'"
