It was narrated from Aws ibn Aws (Radiyallaahu `anhu) that the Prophet (Sallallaahu `alayhi wa sallam) said:

“The best of your days is Friday. On that day Adam (peace be upon him) was created; on that day he died; on that day the Trumpet will be blown and on that day all of creation will swoon.

So send a great deal of blessings upon me, for your blessings will be shown to me.”

They said, “O Messenger of Allah, how will our blessings upon you be shown to you when you have turned to dust?”

He said, “Allah has forbidden the earth to consume the bodies of the Prophets, peace be upon them.”
