Was Khalid sent to Yemen during the time of the Messenger of Allah, may Allah's prayers and peace be upon him, and how many were sent to Yemen during his time, apart from Mu'adh ibn Jabal?

The Prophet, peace and blessings be upon him, sent Khalid ibn al-Walid, Khalid ibn Sa'id, Ali, Abu Musa, and Mu'adh to Yemen. He sent Khalid ibn al-Walid to invite the people of Yemen to Islam, and then he sent Ali to follow him. It is authentically reported in Al-Bukhari and Muslim that the Prophet, peace and blessings be upon him, sent Mu'adh and Abu Musa to Yemen.
