1) I wanted to ask to what extent is a husband supposed to listen to his wife?

2) And also is it a reasonable request to ask him not to go out with his sisters friends even though he is with his sister and his parents are okay with him doing so?

1- A husband must live decently and respectfully with his wife. He must make his marriage successful and without tension. But he does not have to obey his wife and listen to her commands.

2- If his sister’s friends have bad influence on him, then it’s reasonable to ask him not to go out with them.
