Question:
I saw that I was praying maghrib fard when a man (whom I know and admire) calls my name from behind me. I restrain myself from turning to him and when I finish praying he comes to me and we are very happy to see each other.
Answer:
Calling to you from behind during an obligatory prayer indicates he will disrespect your religiosity, and Allah knows best.
