Du'a

Bismillah.

I don't mention my prayers in twitter or facebook. Unless it is a good du'a to be practiced by everyone.
and among best conditions to say our du'a are:
1. In our last sujud.
2. When it is raining
3. In silent and calm moment
4. At the holy land
5. Mistreated by others
6. Travelling (Musafir)
