On the authority of Anas, he said: Qays ibn Saʿd held a position with the Prophet, peace and blessings be upon him, like that of the chief of police with the commander.

Al-Anṣārī said: meaning, among the affairs he managed on his behalf. (1)

This is a ḥasan gharīb ḥadīth (2); we do not know it except from the narration of al-Anṣārī.

4186 - Muḥammad ibn Yaḥyā narrated to us, he said: Muḥammad ibn ʿAbd Allāh al-Anṣārī narrated to us something similar (3), and he did not mention in it the statement of al-Anṣārī.

125 - The Virtues of Jābir ibn ʿAbd Allāh, may God be pleased with them both

4187 - Muḥammad ibn Bashshār narrated to us, he said: ʿAbd al-Raḥmān ibn Mahdī narrated to us, he said: Sufyān narrated to us, on the authority of Muḥammad ibn al-Munkadir, on the authority of Jābir ibn ʿAbd Allāh, he said: The Messenger of God, peace and blessings be upon him, came to me, not riding a mule nor a hack. (4)

This is a ḥasan ṣaḥīḥ ḥadīth.

(1) A sound ḥadīth; al-Bukhārī transmitted it (7155), and it is in "Ṣaḥīḥ Ibn Ḥibbān" (4508), and the statement of al-Anṣārī, "among the affairs he managed on his behalf," is not found in their versions.
(2) In (S): "ḥasan ṣaḥīḥ gharīb," and what is established is from the rest of the sources.
(3) Sound, and see what precedes it.
(4) A sound ḥadīth; al-Bukhārī transmitted it (5664), and al-Nasāʾī in "al-Kubrā" (7459), and it is in "al-Musnad" (15011). And see the preceding ḥadīth numbered (2228), and see the complete citation there. And al-birdhawn: al-Qāḍī ʿIyāḍ said in "al-Mashāriq": al-barādhīn are horses other than the purebred Arabian and the thoroughbred.
