Hadith 8:764
Abu Bakr narrated to us, he said: Abu Dawud al-Tayalisi narrated to us, from Abu Hurrah, from al-Hasan: That he was asked about a man who stood with the Imam, and he detained his mount, and the Imam had already departed, until the crowd dispersed. He said: There is no harm in it.
حدثنا أبو بكر قال حدثنا أبو داود الطيالسي عن أبي حرة عن الحسن أنه سئل عن رجل وقف مع الإمام اتحبس راحلته وقد نفر الإمام حتى يذهب الزحام قال لا بأس به
