Exaggerating in the prostration by increasing the sending of blessings upon the Prophet (peace and blessings be upon him) until I rise from the prostration, and not making du'a for myself: Is my action correct?

Question:
He says: Honorable Shaykh, may Allah grant you success. In the night prayer, in my prostration, after saying "Subhan Rabbi al-A'la" (Glory be to my Lord, the Most High), I do not make du'a for myself, but rather I continue in sending blessings upon the Prophet (peace and blessings be upon him), and I prolong this until I rise from the prostration. Is my action correct?

Answer:
No, regarding the prostration, the Prophet (peace and blessings be upon him) said: "As for the prostration, increase in it " So increase in du'a. Sending blessings upon the Prophet (peace and blessings be upon him) has another place, other than the prostration. Yes.
