question #1 Sahih Muslim 519a, Book 4, Hadith 321 : What can be inferred about the Prophet’s (ﷺ) practice of prayer from his use of a reed mat?

I visited the Apostle (ﷺ) and saw him praying on a reed mat on which he was prostrating himself. And I saw him praying in a single garment with ends crossed with each other.
