Shaykh Albaani was asked:
_‘How should I deal with my neighbor who has removed her Jilbaab that she used to wear, should I boycott her?’_
Shaykh Albaani answers:
‘Boycotting a Muslim as an individual in an Islamic society is like treating a sick person with cauterization, like it has been mentioned in a proverb and in an unauthentic hadeeth: that the last treatment/cure is cauterization so boycotting is the final treatment.
It is not allowed for a Muslim man or woman to be hasty in boycotting the one who has deviated from his Islaam, rather it is upon us to follow them up, by visiting them, by reminding them about their Deen or by refuting them, perhaps they will return and repent.
If we stay with them and become despondent or we waste our time with them and become neglected and we fear this sickness will transfer to other than its source then we say salaam (farewell) to them, we do not seek the ignorant ones.
All praise belongs to Allaah Lord of the Worlds.’
