In short: Every child of Adam is created with 360 joints (Sahih Muslim 1007), and every morning charity is due on each of them. Every SubhanAllah, Alhamdulillah and La ilaha illallah is charity, and two rak’ahs prayed in the forenoon (Duha) are enough for all of it (Sahih Muslim 720).
360 charities a day
Aisha reported that the Prophet ﷺ said each person is created with three hundred and sixty joints, and whoever glorifies Allah, praises Him, removes a stone or thorn from the road, or commands good, to the number of those joints, walks that day having saved himself from the Fire (Muslim 1007).
Two rak’ahs are enough
Abu Dharr reported that charity is due every morning from every bone of the body: every glorification is charity, every praise, every la ilaha illallah, every takbir, enjoining good and forbidding evil. And two rak’ahs prayed in the forenoon suffice for all of that (Muslim 720).
When and how to pray Duha
- Time: after the sun has risen a little (about 15–20 minutes after sunrise) until shortly before Dhuhr. Check sunrise and Dhuhr for your city.
- How: at least two rak’ahs, prayed like any voluntary prayer.
- Also counts: the dhikr in the hadith, so keep up your tasbih after prayer, and small kindnesses: charity without money.
