Hasan Urfi says that once in the presence of Sayyiduna Ibn Abbas (may Allah be pleased with them both), the topic arose that if a dog, a donkey, or a woman passes in front of someone praying, the prayer is broken. He said, "You have not done well by equating a Muslim woman with a dog and a donkey. I remember a time when I myself came riding on a donkey, and the Prophet (peace and blessings be upon him) was leading the people in prayer. When I came close to the Prophet (peace and blessings be upon him) from the front, I got down from it and left it, and joined the prayer with the Prophet (peace and blessings be upon him). The Prophet (peace and blessings be upon him) neither repeated his prayer nor forbade me for what I had done. Similarly, once the Prophet (peace and blessings be upon him) was leading the people in prayer, a little girl came and slipped into the rows and clung to the Prophet (peace and blessings be upon him). The Prophet (peace and blessings be upon him) neither repeated his prayer nor forbade the girl. Also, once the Prophet (peace and blessings be upon him) was praying in the mosque when a kid (young goat) came out from one of the rooms of the Prophet (peace and blessings be upon him) and started to pass in front of him. The Prophet (peace and blessings be upon him) stopped it. Now, why do you not say that the prayer is broken if a kid passes in front of someone praying?"
