If there is any misunderstanding between Husband and Wife, the one who wants to clear this misunderstanding must recite this Surah continuously for seven days, one time a day. Any misunderstanding between Husband and Wife will be eliminated and Love between them will become stronger.
In another place, it is written that if Naqsh of Surah An-Nisa is hanged on any of the walls of home, That home will be safe from every danger.
