question #1 Sahih Muslim 499b, Book 4, Hadith 274 : What is the significance of having an object like the back of a saddle in front of a person during prayer?

We used to say prayer and the animals moved in front of us. We mentioned it to the Messenger of Allah (ﷺ) and he said: If anything equal to the back of a saddle is in front of you, then what walks in front, no harm would come to him. Ibn Numair said: No harm would come whosoever walks in front.
