Sunan an-Nasa'i Book 25, Hadith 108
← Previous Hadith "The sanctity of the wives of the Mujahidin to those who stay behind is like the sanctity of their mothers. There is no man among those who stay behind who takes on the responsibility of looking after the wife of one of the Mujahidin (and betrays him) but he (the betrayer) will be made to stand before him on the Day Resurrection and it will be said: 'O So-and-so, this is so-and-so, take whatever you want from his good deeds.'" Then the Prophet (ﷺ) turned to his Companions and said: "What do you think: Will he leave him any of his good deeds?"
