Hadith 1227
Zaid bin Arqam narrates that the Messenger of Allah (peace be upon him) came upon a group of people while they were performing the Duha prayer in the Quba Mosque after the sun had risen. The Prophet (peace be upon him) said: "The prayer of the Awabeen should be performed at the time when the young camel feels the heat." Imam Abu Bakr (may Allah have mercy on him) also narrated a similar hadith from Zaid bin Arqam through another chain of transmission.
