It is narrated from Hazrat Anas (may Allah be pleased with him) that Hazrat Abu Talha's (may Allah be pleased with him) son—whose name was Abu Umair—used to joke and play with the Prophet (peace and blessings be upon him). One day, the Prophet (peace and blessings be upon him) saw him sad and said, "What is the matter? Abu Umair looks sad." The family told him that his bird, with which he used to play, had died. Upon this, the Prophet (peace and blessings be upon him) said, "O Abu Umair! What happened to the Nughair (the bird that had died)?"
