question #1 Sahih Muslim 504a, Book 4, Hadith 286 : What can be inferred about the permissibility of passing in front of a prayer row from this incident?

I came riding on a she-ass, and I was on the threshold of maturity, and the Messenger of Allah (ﷺ) was leading people in prayer at Mina. I passed in front of the row and got down, and sent the she-ass for grazing and joined the row, and nobody made any objection to it.
