What is the ruling on speech between engaged couples, and is the dullness of feelings and depression resulting from a sense of guilt about it considered a beginning of depression, and what is the legitimate remedy for such a state?

First, we recommend abundant supplication and fervent prayer to Allah Almighty, for He is the Remover of adversity, as He says: "And if Allah should touch you with adversity, there is no remover of it except Him." Second, her profound distress is not surprising, but intense fear is an illness that can lead to despair. Therefore, the door of hope must be opened, and she should be reminded of the immensity of Allah's mercy and forgiveness, and that no sin is too great for His forgiveness, as He says: "Say, 'O My servants who have transgressed against themselves [by sinning], do not despair of the mercy of Allah.'" Third, she should strive to engage in the remembrance of Allah and perform legal ruqyah. There is no harm in righteous people performing ruqyah for her. Fourth, if specialists diagnose depression and prescribe treatment, it is good to use it, and whoever can persuade her may help her calm down. Fifth, completing the marriage may help in her recovery and return to her normal life, and we hope this will be a matter of attention and consultation.
