How accurate is the anasheed "O Amina, good tidings to you, glory be to Him who gave you," which mentions the pregnancy of the Prophet, peace and blessings be upon him, in Rajab and his birth in Rabi' al-Awwal?

The verses are generally sound, but some of what they contain has no basis or its chain of narration has not been authenticated, such as the statement: "The Beloved was born bowing and prostrating." What is narrated about his birth in prostration is weak in its chain of narration. And his statement: "The Beloved was born circumcised, kohled, and oiled." What is narrated about his birth circumcised is very weak, and there is no authentic hadith regarding it. And we have found no basis for his birth kohled and oiled.
