Sahih Muslim Book - 33, Hadith - 4908

حَدَّثَنَا أَبُو بَكْرِ بْنُ أَبِي شَيْبَةَ حَدَّثَنَا وَكِيعٌ عَنْ سُفْيَانَ عَنْ عَلْقَمَةَ بْنِ مَرْثَدٍ عَنْ سُلَيْمَانَ بْنِ بُرَيْدَةَ عَنْ أَبِيهِ قَالَ قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ حُرْمَةُ نِسَاءِ الْمُجَاهِدِينَ عَلَى الْقَاعِدِينَ كَحُرْمَةِ أُمَّهَاتِهِمْ وَمَا مِنْ رَجُلٍ مِنْ الْقَاعِدِينَ يَخْلُفُ رَجُلًا مِنْ الْمُجَاهِدِينَ فِي أَهْلِهِ فَيَخُونُهُ فِيهِمْ إِلَّا وُقِفَ لَهُ يَوْمَ الْقِيَامَةِ فَيَأْخُذُ مِنْ عَمَلِهِ مَا شَاءَ فَمَا ظَنُّكُمْ ؟.

It was narrated from Sulaiman bin Buraidah that his father said: "The Messenger of Allah (s.a.w) said: 'The sanctity of the wives of the Mujahidin for those who stay behind is like the sanctity of their own mothers. There is no man among those who stay behind who looks after the family of one of the Mujahidin and then betrays him with regard to them, but he will be made to stand on the Day of Resurrection, and he (the Mujahid) will take as much of his good deeds as he wishes; so what do you think?'"
