Were there poets for the Messenger of Allah, may Allah bless him and grant him peace, other than Hassan ibn Thabit?

The Prophet, peace and blessings be upon him, had three poets: Ka'b ibn Malik, Hassan ibn Thabit, and Abdullah ibn Rawahah. The Messenger of Allah, peace and blessings be upon him, said about them: "Indeed, the mujahid (striver in the path of Allah) strives with his sword and his tongue. By Him in Whose Hand is my soul, it is as if you are showering them with arrows." Each of them specialized in a style: Ka'b would mention war and threats, Hassan would mention faults and historical events, and Ibn Rawahah would mock disbelief. As for Ka'b ibn Zuhayr, he praised the Prophet, peace and blessings be upon him, but he was not considered one of the Prophet's poets.
