Will you give information about Khalid b. Walid's killing the tribe of Jazima and the attitude of the Prophet about it?

After the conquest of Makkah, Khalid bin Walid was appointed to capture the tribes that did not accept Islam. Meanwhile, those tribes started to accept Islam and go to the Prophet (pbuh). However, they were killed by Walid. When the Prophet heard it, he tapped Walid on the back. To what extent is this narration true?

Dear Brother / Sister,

The conquest of Makkah is remarkable in terms of the practices of the Prophet about the new Muslims.  After the conquest, the people of Makkah were not treated as if they were a nation that was defeated and inhabitants of a region that was invaded. On the contrary, they were elevated to the same level as those who defeated them in terms of rights and duties. Nobody’s wealth, house and property was grabbed. They were not regarded as booty.  

After the conquest, the mujahids did not spend the night by plundering; on the contrary, they spent the night by uttering Allahuakbar and La ilaha illallah and circumambulating the Kaaba until the morning.

The Prophet borrowed one hundred and thirty thousand dirhams from three rich people of Makkah and gave them to the Companions who were in need. Afterwards, he paid this debt through the booty of Hawazin. The Prophet did not leave any soldiers in Makkah and moved toward Hunayn; he appointed Attab b. Asid, a Makkan who had just become a Muslim, as the administrator of Makkah.  

After breaking the idol Uzza, Khalid b. Walid returned; the Prophet (pbuh) sent him to the tribe of Jazima b. Amir in the month of Shawwal to invite them to Islam. Khalid, who was not sent to fight them, went to Ghumays, which was the land of the tribe of Jazima, with a military unit of 350 soldiers including Muhajirs, Ansar and the tribe of Sulaym. The tribe of Sulaym confronted them with their weapons. Khalid wanted them to leave their weapons. They fulfilled his order and said, "Saba'na" meaning "we changed our religion". Khalid was not convinced that they had become Muslims. He reminded them they had cooperated with the enemies of Islam in the past; he enslaved them and distributed them among soldiers. The next morning, he told his soldiers to kill them. Thereupon, Sons of Sulaym killed about thirty slaves that they had. However, the soldiers of Muhajirs and Ansar did not obey Khalid and freed the slaves.

When the Prophet (pbuh) was informed about the incident, he became very sorry; he did not approve what Khalid did and said he was away from what Khalid did. Then, he sent Hz. Ali to the tribe of Jazima and paid blood money for the people killed during the incident.
