It is narrated from Sayyiduna Anas bin Malik (may Allah be pleased with him) that Abu Talha (may Allah be pleased with him) had a son from Sayyida Umm Sulaym (may Allah be pleased with her), whose name was Abu Umair (may Allah be pleased with him). When the Messenger of Allah (peace and blessings be upon him) would visit their house, he used to joke with him. Sayyiduna Abu Umair (may Allah be pleased with him) had a bird called Nughayr (bulbul). One day, the Messenger of Allah (peace and blessings be upon him) went and saw that Abu Umair (may Allah be pleased with him) was sad. He (peace and blessings be upon him) asked: "What has happened to him?" It was told that his bird (Nughayr) had died. So the Messenger of Allah (peace and blessings be upon him) said: "O Abu Umair! What did the Nughayr do?"
