What is the ruling of Islamic law concerning a husband who accuses his wife of infidelity without proof and threatens to kill her family with a machine gun, which forced them to leave the house?

Satan is an enemy to man and seeks to sow discord among loved ones, especially between spouses. A husband accusing his wife and slandering her honor is a temptation from Satan. The default is the wife's innocence until proof is presented for what the husband accuses her of. We advise praying to Allah for the betterment of the situation and seeking help from those who can influence the husband. The wife should avoid doubtful situations, especially in such circumstances.
