Buraidah (May Allah be pleased with him) said:
The Messenger of Allah (ﷺ) said, "The sanctity of the wives of Mujahidun (i.e., those who strive hard and fight in the way of Allah) for those who remain at home (i.e., those who do not go to the battlefield to fight Jihad) is like the sanctity of their own mothers. Anyone who remains behind to look after the family of a Mujahid and betrays his trust, will be made to stand on the Day of Resurrection before the Mujahid who will take away from his meritorious deeds whatever he likes till he is satisfied." The Messenger of Allah (ﷺ) turned toward us and said, "Now, what do you think (i.e., will he leave anything with him)?"[Muslim].
