From Sahih Muslim (Hadith 1112):
Musa b. Talha reported on the authority of his father: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
