question #1 Sahih Muslim 458b, Book 4, Hadith 190 : How did the Prophet Muhammad (ﷺ) perform his prayers in terms of length and recitation?

He (the Holy Prophet) shortened the prayer and he did not pray like these people then, and he informed me that the Messenger of Allah (ﷺ) used to recite” Qaf. By the (Glorious) Qur’an,” and a passage of similar length.
