Question

The imam doesn't make dua after namaz. He just sits and makes his own tasbeeh and stands up after few mins after making salaam. Sometimes after making his tasbeeh he raises his hands and makes his own silent dua 2 3 mins after namaz has ended. This is rare also. Is this correct?

Answer

Nothing bad in it. Its all right.
