How can one deal with a father's intense jealousy towards the mother, which affects her freedom and her relationship with her children? What steps can the father take? Is it permissible to recite Quranic verses over the father for his healing from jealousy, and if so, which verses?

Jealousy is of two types: praiseworthy and blameworthy. A father's jealousy of his wife with her children is blameworthy because it only arises when there is suspicion, and in this case, it is a satanic whisper and a bad assumption. The father must seek refuge in Allah from this ailment and have a good opinion of his family. The questioner should play the role of a righteous advisor with wisdom and good counsel, while being cautious of anything that angers the father. Reading the Qur'an is a cure for him.
