Sheikh Tabarsi in amali, quoting from Ibn Amalah, narrated from the Prophet, no servant will enter Paradise unless there are two holy angels, one sitting near his head and the other near his feet singing, and that is a song that neither man nor jinn have heard, and that song is not sung with evil moods, but is associated with the extension and sanctification of Dear God.
Also, Sheikh Tabarsi has narrated in his amali citing Ibn Darda that one day the Prophet was speaking to a crowd in the mosque about heaven and its blessings. At that moment, a man stood up from the crowd and said, “O Prophet, is there a song to be heard in heaven?”
He said yes Arab, indeed there is a river in heaven surrounded by women who are made of light, singing a song that no creature has ever heard, and that song is the best thing in heaven. The narrator says the Prophet was asked what they are singing with, He said, by God`s hallelujah.[1]
