Kindly tell me that how I'm able to know that Imam-e-Zamana (ATFS) is agreeing with me. I mean whatever I'm doing (Aamaal) in my daily routine he is seeing all that so if I want to know that Imam MEehdi (ATFS) is happy with all my activities or not then what can I do or how can I able to know that?
Kindly, explain me in detail what I do to make my time of Imam agree and happy with me.

You have to do what makes Imam A S happy, and leave what makes him unhappy.
Piety of Allah SWT is the most important thing you should take care of.
Always recite your prayers on time with devout.
When you do these things, Imam will be happy with you.
