Sayyiduna al-Fadl bin Abbas (may Allah be pleased with him) narrated: The Messenger of Allah (peace and blessings be upon him) came to Sayyiduna al-Abbas (may Allah be pleased with him) at a desert place of ours. He prayed Asr while a female dog of ours or a female donkey of ours was in front of him; he did not stop it, nor did we move it back.
