So that man went to the service of the Prophet (peace and blessings be upon him) and told him what the Ansar had said. The Prophet (peace and blessings be upon him) said: "The Ansar have done well.

He (peace and blessings of Allah be upon him) asked, "What is the matter with him?" It was said to him, "His nightingale has died." The Prophet (peace and blessings of Allah be upon him) said, "O Abu Umair! What happened to your nightingale? It has left you."

It is narrated from Sayyiduna Abdullah bin Zubair (may Allah be pleased with him) that Sayyidah Aisha (may Allah be pleased with her) said: O Messenger of Allah!
