Lengthening the final prostration in voluntary prayer

Question:
He says: Honorable Shaykh, may Allah grant you success. A man prays the sunnah prayers and he lengthens the final prostration of every sunnah prayer. One of the students of knowledge objected to him, saying that lengthening the final prostration of every rak'ah is not established, and that this statement is from you, Honorable Shaykh, may Allah grant you success.

Answer:
Yes, yes, I am the one who says this. This is the sunnah (recommended practice) of the Messenger of Allah (peace and blessings be upon him). The Messenger (peace and blessings be upon him) used to lengthen the bowing and prostration in the first two rak'ahs, and then in the final rak'ahs he would shorten them slightly. The Messenger of Allah (peace and blessings be upon him) would progress gradually in his prayer. He did not do the opposite, starting with a short prayer and then lengthening it. No, he would lengthen the beginning and then shorten the end. Yes, his prayer would be gradual. Yes.
