Anas b. Malik said :The Messenger of Allah (May peace be upon him) used to come to visit us. I had a younger brother who was called Abu ‘Umair by Kunyah (surname). He had a sparrow with which he played, but it died. So one day the prophet (May peace be upon him) came to see him and saw him grieved. He asked: What is the matter with him? The people replied: His sparrow has died. He then said: Abu ‘Umair! What has happened to the little sparrow?
