What is the correct way to perform the prayers, taking into account the multiplicity of opinions and the diversity of supplications used in each prayer?

The correct prayer is performed as the Prophet, peace and blessings be upon him, used to perform it, based on his saying: "Pray as you have seen me praying." The Companions transmitted the manner of his prayer through continuous, successive narration (tawatur), and it was recorded in the books of the people of knowledge. Differences in some minor details, such as the Sunan (recommended acts) and Mustahabbat (desirable acts), do not cause harm. Among the supplications in prayer are: the opening supplication (du'a al-istiftah) after the opening takbir, saying "Subhan Rabbi Al-Adhim" (Glory be to my Lord, the Most Great) in bowing (ruku'), "Subhan Rabbi Al-A'la" (Glory be to my Lord, the Most High) in prostration (sujud), "Rabbighfir li" (My Lord, forgive me) between the two prostrations, the tashahhud, seeking forgiveness after the taslim, and glorifying, praising, and magnifying God after the prayer.
