[Unnumbered note] The hadith is transmitted from Abu Hurayra through several chains: Ahmad, 2:254 (Aswad b. Amir → Jarir b. Hazim → al-Hasan → Abu Hurayra); 2:329 (Abu al-Nadr → al-Mubarak → al-Hasan → Abu Hurayra); 2:174 (Yahya → Imran Abu Bakr → al-Hasan → Abu Hurayra). Al-Nasa’i, 4:218, records it through Muhammad b. Rafi‘ → Abu al-Nadr → Abu Mu‘awiya → ‘Asim → al-Aswad b. Hilal → Abu Hurayra. Ahmad, 2:484, cites the route of Yunus → al-Khazraj → Abu Ayyub → Abu Hurayra, and again at 2:271 and 489 via two further chains: Qatada → al-Hasan → Abu Hurayra. The wording is: “The Messenger ﷺ enjoined me to keep three practices which I shall never abandon whether at home or travelling: to sleep after performing witr, to fast three days of every month, and to pray two rak‘as of the duha prayer.” Al-Hasan later erred and substituted “the Friday ghusl” for the duha prayer. The same text, without passing through al-Hasan, is narrated from Abu Hurayra by al-Bukhari (1178, 1981); Muslim (721); al-Darimi 1:339; 2:18; Abu Dawud (1432); and Ahmad 2:258, 277, 402, 459, 505.

(1) The hadith of Abu Umair is reported by al-Bukhari (1629, 6203), Muslim (2150), Abu Dawud (4969) and al-Tirmidhi (333) on the authority of Anas: “The Prophet ﷺ was the kindest of people. I had a little brother called Abu Umair—I think he had been weaned. Whenever the Prophet came he would say, ‘Abu Umair, what happened to the nughayr?’—a small bird he used to play with. Sometimes the time for prayer arrived while he was in our house, and he would order that the mat beneath him be swept and sprinkled; then he would stand and we would line up behind him to pray.” The nughayr is a small bird resembling a sparrow. Ibn al-Qass devoted a treatise to this hadith, opening with the remark that some people faulted the hadith scholars for transmitting reports they deemed useless, citing this narration as an example. He replied that this single hadith contains sixty points of fiqh, etiquette and benefit, which he set out in detail; al-Hafiz Ibn Hajar later summarised them in full.
