Sayyiduna Ibn Abbas (may Allah be pleased with them both) said: One day the Messenger of Allah (peace and blessings be upon him) was praying when a young goat began to pass in front of him (peace and blessings be upon him), so he (peace and blessings be upon him) hastened (to stop it). And the Messenger of Allah (peace and blessings be upon him) was praying while a female donkey belonging to al-Fadl bin Abbas (may Allah be pleased with him) was grazing in front of him (peace and blessings be upon him) that day.
