حَدَّثَنِي مَالِكٌ، عَنْ صَفْوَانَ بْنِ سُلَيْمٍ، أَنَّ رَجُلاً، قَالَ لِرَسُولِ اللَّهِ صلى الله عليه وسلم أَكْذِبُ امْرَأَتِي يَا رَسُولَ اللَّهِ فَقَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم ‏"‏ لاَ خَيْرَ فِي الْكَذِبِ ‏"‏ ‏.‏ فَقَالَ الرَّجُلُ يَا رَسُولَ اللَّهِ أَعِدُهَا وَأَقُولُ لَهَا فَقَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم ‏"‏ لاَ جُنَاحَ عَلَيْكَ ‏"‏ ‏.‏
