Sahih Ibn Khuzaymah

Imam Abu Bakr, may Allah have mercy on him, says that the apparent meaning of this hadith is also like the hadith of Ubaidullah bin Abdullah from Sayyiduna Ibn Abbas, may Allah be pleased with them both, that the donkey passed in front of the companions of the Noble Prophet, peace and blessings be upon him, and not in front of the Noble Prophet, peace and blessings be upon him, himself. And in this hadith, it is also not mentioned that the Noble Prophet, peace and blessings be upon him, was aware of this matter. But even if it had been mentioned in the hadith that the Noble Prophet, peace and blessings be upon him, became aware that the donkey had passed in front of some of his followers, still the sutrah of the Noble Prophet, peace and blessings be upon him, would have been sufficient for his followers. Because when the Noble Prophet, peace and blessings be upon him, used to lead the prayer in the Eid ground, he would make a spear as a sutrah. And if the sutrah of the Noble Prophet, peace and blessings be upon him, was not considered a sutrah for the followers, then every worshipper would have had to make a sutrah with a spear like the Noble Prophet, peace and blessings be upon him. Therefore, the raising of the spear as a sutrah for the Noble Prophet, peace and blessings be upon him, and his not commanding the followers to make a (separate) sutrah, is evidence that the sutrah of the imam is the sutrah of the followers.
