What is the way to control severe anger and excessive nervousness that lead to serious marital problems, especially in light of the wife's actions that intensify the anger, and the fear of the impact of that on the children and their memorization of the Qur’an?

You have diagnosed the illness and the cure; all that remains is a firm resolve to repel anger by seeking Allah's help, exercising patience, changing circumstances, performing ablution, and remembering Allah. We advise you to be gentle with your sensitive and nervous wife, to consider her feelings, and to be patient with her, because her eagerness to teach the Quran is a good quality in her. Her lack of love is not a justification for divorcing her, for not all homes are built on love. Marital problems can be overcome with wisdom, patience, prioritizing what is beneficial, and guarding against Satan, who is keen on causing separation, and by using people of good will as mediators for reconciliation. Teaching the Quran to a child has immense reward, and you are right in dedicating time for revision, while leaving some flexibility for the child so that he does not become bored or dislike learning.
