Shaykh Muhammad Nasiruddin Al-Albani was asked a question:

Questioner:

“A Salafi brother [for the sake of Allah] lives with me. However, he shortens his beard and persists upon that. So how do I interact with him while I have given him advice [already]?

Shaikh:

There is nothing upon you except advice and following up with reminders. And that you bring him an evidence which is necessary for him [to follow]. Then ask Allah to grant him guidance.

Questioner:

A brother advised me to boycott him. Should I boycott him so that he returns to his affair?

Shaikh:

Do not boycott him. If you boycott someone because he trims his beard, then the meaning [of that] is that it is necessary for you to retreat to the tops of the mountains [i.e. Leave society altogether]”

[Silsilatul-Huda wan-Nur (no. 19)]
