Thumāmah ibn Anas ibn Mālik

On the authority of Anas ibn Mālik, who said: The Messenger of Allah, peace and blessings be upon him, said: "Whoever prays the Duḥā prayer twelve rakʿahs, Allah will build for him a palace of gold in Paradise."(1)

On this topic, there are also reports from Umm Hāniʾ, Abū Hurayrah, Nuʿaym ibn Hammār, Abū Dharr, ʿĀʾishah, Abū Umāmah, ʿUtbah ibn ʿAbd al-Sulamī, Ibn Abī Awfā, Abū Saʿīd, Zayd ibn Arqam, and Ibn ʿAbbās.

The ḥadīth of Anas is gharīb(2); we do not know it except through this chain of transmission.

478 — Abū Mūsā Muḥammad ibn al-Muthannā narrated to us, saying: Muḥammad ibn Jaʿfar narrated to us, saying: Shuʿbah informed us, on the authority of ʿAmr ibn Murrah, on the authority of ʿAbd al-Raḥmān ibn Abī Laylā, who said:
No one told me that he saw the Prophet, peace and blessings be upon him, pray the Duḥā prayer except Umm Hāniʾ, for she narrated that the Messenger of Allah, peace and blessings be upon him, entered her house on the day of the conquest of Mecca, performed a ritual bath, and then prayed eight rakʿahs. I never saw him pray any prayer lighter than it, except that he completed the bowing and prostration(3).

(1) Its chain of transmission is weak; Mūsā ibn Fulān — and it is said: ibn Ḥamzah — is unknown.
It was also recorded by Ibn Mājah (1380), al-Ṭabarānī in al-Awsaṭ (3967) and in al-Ṣaghīr (506), and al-Baghawī in Sharḥ al-Sunnah (560).
(2) In copy (B) alone: ḥasan gharīb.
(3) A sound ḥadīth; it was also recorded by al-Bukhārī (1103), (1176), and (4292), Muslim p. 497 (80), Abū Dāwūd (1290) and (1291), and Ibn Mājah (1323). It is in al-Musnad (26900) and Ṣaḥīḥ Ibn Ḥibbān (1188).
