Praise be to Allaah.
The believer should think well of others, assume the best
and keep away from doubt and suspicion that have no basis, because Allah
says (interpretation of the meaning): “O you who believe! Avoid much
suspicion; indeed some suspicions are sins. And spy not” [al-Hujuraat
This Qur’aanic etiquette is one of the means of peace of
mind, happiness and comfort, because suspicion prompts one to search and try
to find out, and it may lead to spying, and that is usually accompanied by
worry, anxiety and distress.
But if there are things that call for doubt and suspicion,
the husband has to try to remedy the matter and set things straight, and to
block the ways that may lead to fitnah and evil. If the wife -- for example
-- gets in touch with people or corresponds with them or is away from the
house without any convincing reason and the like, then he may prevent her
from doing that. If he is worried about her staying on her own in the house,
he can bring her to live near his family or righteous neighbours.
We have previously discussed the ruling on setting up
recording devices to keep an eye on family conversations. See the answer to
question number 13318.
And Allah knows best.
