(21) باب تَحْرِيمِ إِفْشَاءِ سِرِّ الْمَرْأَةِ
Abu Sirma al-Khudri (Allah he pleased with him ) reported Allah's Messen- ger (ﷺ) as saying:
The most important of the trusts in the sight of Allah on the Day of judgment is that a man goes to his wife and she goes to him (and the breach of this trust is) that he should divulge her secret Ibn Numair narrates this hadith with a slight change of wording.
