Is it permissible for a husband to prevent his wife from using social media without a reason, and is he entitled to search her phone under the pretext of knowing her relationships and correcting what he deems deviant?

A husband should not prevent his wife from using social media unless there is a suspicion that necessitates it. Otherwise, this might lead to distrust or her using them secretly. The husband should raise his wife well so that he does not need to make such decisions. If the husband forbids her due to fear of corruption, she must obey him because obedience to the husband in what is permissible is obligatory, especially since these platforms have become among the most dangerous means of corruption. Spying is forbidden unless there is suspicion. With suspicion, spying is permissible to the extent of the need.
