On the authority of Ibn ʿUmar, from the Prophet, peace and blessings be upon him, who said: "The prayer of the night and the day is two by two."(1)

1296 – Ibn al-Muthannā narrated to us, Muʿādh ibn Muʿādh narrated to us, Shuʿbah narrated to us, ʿAbd Rabbih ibn Saʿīd narrated to me, from Anas ibn Abī Anas, from ʿAbd Allāh ibn Nāfiʿ, from ʿAbd Allāh ibn al-Ḥārith, from al-Muṭṭalib, from the Prophet, peace and blessings be upon him, who said: "The prayer is two by two: that you recite the tashahhud..."

--------------------------------------------
(1) Its chain is sound, except that the reliable narrators among the companions of Ibn ʿUmar did not mention in it the daytime prayer. Al-Dāraquṭnī said in al-ʿIlal: The mention of the daytime in it is an error.
ʿAlī al-Bāriqī: He is ʿAlī ibn ʿAbd Allāh al-Azdī, and al-Bāriqī is a relative attribution to Bāriq: a mountain where the Azd used to dwell, so he was attributed to it.
It was also recorded by Ibn Mājah (1322), al-Tirmidhī (603), and al-Nasāʾī in al-Kubrā (474) via two paths from Shuʿbah, with this chain.
Al-Tirmidhī said: The companions of Shuʿbah differed regarding it; some raised it to the Prophet, and some stopped it at Ibn ʿUmar, and the reliable narrators narrated it from ʿAbd Allāh ibn ʿUmar, from the Prophet, peace and blessings be upon him, and did not mention in it the daytime prayer. Al-Nasāʾī said in al-Mujtabā: This hadith is in my view an error, and he said in al-Sunan al-Kubrā: Its chain is sound, except that a group of the companions of Ibn ʿUmar contradicted al-Azdī regarding it, and did not mention the daytime in it, among them Sālim, Nāfiʿ, and Ṭāwūs. Then he cited the narration of the three.
It is in Musnad Aḥmad (4791) and Ṣaḥīḥ Ibn Ḥibbān (2482).
It was also recorded without his saying "and the day" by al-Bukhārī (993), (995), and (1137), Muslim (749) (146), (147), and (157), Ibn Mājah (1174), (1175), (1318), and (1320), al-Tirmidhī (465), and al-Nasāʾī (1667–1669), (1672), and (1674) via multiple paths from Ibn ʿUmar.
