Khair 3

Soudabeh:
Allah considers the act as Khair (good) that is defined in the realm of the Imam.
Each action has a begining,  continuation and end. 
The rules of the begining of the act is related to Maghreb to Isha, continuation of the act is related to morning to noon and the result of the act is related to Asr (evening).

What is the feature of this planning? 
There is a connection between human deeds and they aren't separated. Human acts vary in their various situation. If it was supposed that an action  be Khair (good) and pure, its continuity should also be Khair (good) and pure. In fact, the act takes on different appearances just like night and day.
All human mistakes are due to not seeing this continuity of the act. 
Hazrat Amir Al _Moumenin ( Commander of the faithfuls) says: " every act that  you perform should be in a chain."
