وَعَنْهُ أَيْضًا قَالَ قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ إِنَّ مِنْ أَعْظَمِ الْأَمَانَةِ عِنْدَ اللَّهِ يَوْمَ الْقِيَامَةِ الرَّجُلَ يُفْضِي إِلَى امْرَأَتِهِ وَتُفْضِي إِلَيْهِ ثُمَّ يُنْشِرُ سِرَّهَا
It is also narrated from Sayyiduna Abu Sa'id (may Allah be pleased with him) that the Noble Prophet (peace and blessings be upon him) said: The greatest betrayal in the sight of Allah on the Day of Resurrection will be that a man goes to his wife and a woman goes to her husband, and then he begins to disclose her secret.
