Duha Prayer

 Abu Dharr reported Allah's Apostle (may peace be upon him) as saying: In the morning charity is due from every bone in the body of every one of you. Every utterance of Allah's glorification is an act of charity. Every utterance of praise of Him is an act of charity, every utterance of profession of His Oneness is an act of charity, every utterance of profession of His Greatness is an act of charity, enjoining good is an act ofcharity, forbidding what is distreputable is an act of charity, and two rak'ahs which one prays in the forenoon will suffice.  (Book #004, Hadith #1557)

Ahmad and Abu Daw'ud record from Buraidah that the Prophet (SAW) said: In a human (body) there are 360 joints and man must perform an act of charity for each one." The people said: "Who can do that, O Messenger of Allah?" He responded: "One may cover the mucus that one finds in the masjid or remove something harmful from the road. If one cannot do that, he can pray two rak'ahs of Duha and that will be sufficient for him". (Fiqh us Sunnah)

So, as you can no doubt see, we are pretty much expected to do Duha prayer. 

It's time: From when the sun is about a spears length above the horizon until the sun reaches it's meridian. Preferrably delay it until the sun has risen high, and the day has become hot. So, in english about an hour after sunrise until about an hour before duhr should be good. 

The number of Rakaa's: The previous hadith mention doing two, which is the minimum number, but, you can pray as much as you like really. (See Fiqh us Sunnah).

And that's it! Wasn't that easy?
