a) Narrated Ibn Abî Lailâ: Only Umm Hânî told us that she had seen the Prophet صلى الله عليه وسلم offering the Duha (Forenoon prayer). She said. "On the day of the conquest of Makkah, the Prophet صلى الله عليه وسلم took a bath in my house and offered eight Raka‘ât. I never saw him praying such a light prayer but he performed perfect prostrations and bowings". (Sahih Al-Bukhari, Vol.2, Hadith No.207A).
b) Narrated Abu Hurairah رضي الله عنه : My friend (the Prophet) advised me to observe three things:
(1) to fast three days a month;
(2) to pray two Raka‘ât of Duha prayer (Forenoon prayer); and
(3) to pray Witr before sleeping. (Sahih Al-Bukhari, Vol.3, Hadith No.202).
