The Prophet ﷺ said, "The sanctity of the wives of those who go out to fight in the way of Allah is binding upon those who stay behind, just like the sanctity of their own mothers. There is no man among those who stay behind who takes charge of the family of one who has gone out to fight, then betrays him in his family, except that he will be set up for him on the Day of Resurrection, and it will be said, 'So-and-so, this is so-and-so, so take whatever you wish from his good deeds.'"Then the Prophet ﷺ turned to his companions and said, "What do you think? Do you suppose he will leave any of his good deeds for him?"
أخبرنا عبد الله بن محمد بن عبد الرحمن قال حدثنا سفيان قال حدثنا قعنب كوفي عن علقمة بن مرثد
عن النبي ﷺ قال حرمة نساء المجاهدين على القاعدين في الحرمة كأمهاتهم وما من رجل من القاعدين يخلف رجلا من المجاهدين في أهله إلا نصب له يوم القيامة فيقال يا فلان هذا فلان فخذ من حسناته ما شئت ثم التفت النبي ﷺ إلى أصحابه فقال ما ظنكم ترون يدع له من حسناته شيئا
