Narrated ‘abdu ALlaah ibn ‘Umar (رَضِيَ الله عَنْهُمَا) that the messenger of Allaah (صَلَّى للَّهُ عَلَيْهِ وَسَلَّمَ) said:
“He who prays ad-Doha, fasts three days every month and does not abandon Witr neither travelling nor at residence, will have the reward of a martyr written for him”
[atTabarani in Muyamma’ azZawa’ed (241/2), declared saheeh by sheikh al-Albani (rahimahu Allaah) in sahih at-Targhib wa Taarhib, no. 595]
Note: ad-Doha starts when the sun raises the length of a spear (approximately 10 to 20 minutes after sunrise) and ends about 15 to 30 minutes before the adhan for duhr, it is prayed in pairs of rakats and can consist of at least two, to as many rakat as you would like beyond that.

Abu Hurairah (May Allah be pleased with him) reported:
My friend (the Messenger of Allah) (sallallaahu ’alayhi wa sallam) directed me to observe fast for three days in every month, to perform two Rak`ah (optional) Duha prayer at forenoon and to perform the Witr prayer before going to bed.
