Dealing with colleagues who openly commit sins and boycotting them

The questioner:
(peace and blessings be upon him) Some people, meaning colleagues at work, may be shaven or may be openly committing sins. So, does one show him a friendly face when greeting him?

The Shaykh:
He should advise him, advise him and direct him to good before the advice, and he should not boycott him.

The questioner:
If Allah wills. Peace be upon you, young men.

The Shaykh:
If he makes the sin apparent.

The questioner:
The persistence in shaving the beard.

The Shaykh:
This is an open disobedience.

The questioner:
You?

The Shaykh:
And smoking in front of people is an open disobedience. Yes.

The questioner:
It may be tolerated, meaning this is a case at work, meaning the issue of smoking may be tolerated, but shaving is open, meaning it is all open.

The Shaykh:
Correct, directing him to good.

The questioner:
And otherwise, it is recommended.

The Shaykh:
The right to boycott.
