It was narrated from Sulaiman bin Buraidah, from his father, that the Messenger of Allah صلی اللہ علیہ وآلہ وسلم said: “The sanctity of the wives 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?” (Sahih)
