It was narrated from Sulaiman bin Buraidah, from his father, that the Messenger of Allah ﷺ said:

"The sanctity of the wive of the Mujahidin to those who stay behind is like the sanctity of their mothers. If he takes on the responsibility of looking after his wife then betrays him, it will be said to him on the Day of Resurrection: 'This one betrayed you with your wife, so take whatever you want of his good deeds.' So what do you think?"

أَخْبَرَنِي هَارُونُ بْنُ عَبْدِ اللَّهِ، قَالَ حَدَّثَنَا حَرَمِيُّ بْنُ عُمَارَةَ، قَالَ حَدَّثَنَا شُعْبَةُ، عَنْ عَلْقَمَةَ بْنِ مَرْثَدٍ، عَنْ سُلَيْمَانَ بْنِ بُرَيْدَةَ، عَنْ أَبِيهِ، أَنَّ رَسُولَ اللَّهِ ﷺ قَالَ " حُرْمَةُ نِسَاءِ الْمُجَاهِدِينَ عَلَى الْقَاعِدِينَ كَحُرْمَةِ أُمَّهَاتِهِمْ وَإِذَا خَلَفَهُ فِي أَهْلِهِ فَخَانَهُ قِيلَ لَهُ يَوْمَ الْقِيَامَةِ هَذَا خَانَكَ فِي أَهْلِكَ فَخُذْ مِنْ حَسَنَاتِهِ مَا شِئْتَ فَمَا ظَنُّكُمْ " .
