"O Allah, I declare myself innocent before You of what Khalid has done," twice (1).

18 - Chapter: Mention of what a ruler should avoid

5406 - Qutaybah ibn Sa'id informed us, saying: Abu 'Awanah narrated to us, from 'Abd al-Malik ibn 'Umayr, from 'Abd al-Rahman ibn Abi Bakrah, who said:

My father wrote — and I wrote on his behalf — to 'Ubayd Allah ibn Abi Bakrah, who was the judge of Sijistan: Do not judge between two people while you are angry, for I heard the Messenger of Allah, peace and blessings be upon him, say: "No one should judge between two people while he is angry" (2).

(1) Both of its chains of transmission are authentic. Ma'mar: he is ibn Rashid, and al-Zuhri: he is Muhammad ibn Muslim, and Salim: he is ibn 'Abd Allah ibn 'Umar. It is in "Al-Sunan al-Kubra" under number (5922) with the second chain of transmission.
Al-Bukhari also narrated it (4339) and (7189) from Nu'aym ibn Hammad, from 'Abd Allah ibn al-Mubarak, with the first chain of transmission.
It is found with 'Abd al-Razzaq in "Al-Musannaf" (9434) and (18721), and from his narration Ahmad narrated it (6382), al-Bukhari (4339) and (7189), al-Musannif in "Al-Sunan al-Kubra" (8542), and Ibn Hibban (4749).
Al-Bukhari attached a portion of it following the two hadiths (3172) and (6340), which is his saying: Khalid began killing, so the Prophet, peace and blessings be upon him, said: "I declare myself innocent before You of what Khalid has done."
Al-Sindi said regarding his saying "we became Sabians": meaning we left the religion of our fathers for the religion to which we were being called, and they intended by that to show their entry into Islam, for the disbelievers used to call the Muslim "al-Sabi'" at that time. However, since the wording was not explicit regarding Islam, Khalid permitted killing them. "Of what Khalid has done" — of killing those who showed that their intention was Islam.

(2) Its chain of transmission is authentic. Abu 'Awanah: he is al-Waddah ibn 'Abd Allah al-Yashkuri.
Muslim narrated it (1717), and al-Tirmidhi (1334), both from Qutaybah, with this chain of transmission.
Ahmad narrated it (20379), (20389), (20393), (20467), and (20522), al-Bukhari (7158), Muslim (1717), Abu Dawud (3589), al-Musannif in "Al-Kubra" (5923), Ibn Majah (2316), and Ibn Hibban (5063) and (5064) through various routes from 'Abd al-Malik ibn 'Umayr, with it. =
