What is the ruling on the prayer of one who only says "Subhana Rabbiyal A'la" during prostration for recitation, and says "Allahu Akbar" when rising?

The questioner is not accountable for what has passed. In the future, it is prescribed for the prostration of recitation (Sujud al-Tilawah) to say what is said in the prostration of prayer (Sujud as-Salah). If one says: "My face has prostrated to the One Who created it, and fashioned its hearing and sight by His might and power," that is good. One should pronounce the takbir (Allahu Akbar) when descending for prostration and when rising from it, whether in prayer or outside of it.
