Abu al-Sahba' (may Allah have mercy on him) relates: We were with Sayyiduna Abdullah bin Abbas (may Allah be pleased with them both), and the people mentioned what breaks the prayer. Someone said: "A dog, a woman and a donkey." Sayyiduna Abdullah bin Abbas (may Allah be pleased with them both) said: "A boy from Banu Hashim, or Banu Abd al-Muttalib, and I came riding together on one donkey while the Messenger of Allah (peace and blessings be upon him) was leading the people in prayer in open ground. We got down from the donkey and left it in front of them, and they paid no attention to it. Two little girls of Banu Hashim came running and started fighting, so the Messenger of Allah (peace and blessings be upon him) took hold of them and separated them from each other, and paid no attention to it."
