All perfect praise be to Allaah, The Lord of the Worlds. I testify that there is none worthy of worship except Allaah, and that Muhammad is His slave and Messenger. We ask Allaah to exalt his mention as well as that of his family and all his companions.
We supplicate Allaah to dispel your grief, remove your sorrow and reconcile your parents. We guide you to some important matters:
First, supplicate Allaah as much as possible to reconcile your parents. Make supplications at the recommended times when supplications are more likely to be responded to, such as the last third of the night, during prostration, between Athaan and Iqaamah, and the like.
Second, arrange separate meetings with each of your parents and let them know your feelings regarding the unhappy incidents that are taking place. Try to address them in an appealing way and express your feelings, probably they may become soft and prepare to settle their disputes.
Third, try to convince them to appoint some wise and reliable persons from their families or scholars to look into their matters and settle them.
Fourth, they should be reminded of Allaah and His commands about being good with one's spouse. Allaah says (interpretation of meaning): {…And due to them [i.e. the wives] is similar to what is expected of them, according to what is reasonable….}[2:228]. Your mother especially should be reminded of that her husband is her caretaker and should be obeyed. Allaah says (interpretation of meaning): {Men are in charge of women by [right of] what Allah has given one over the other and what they spend [for maintenance] from their wealth…..}[4:34].
On the other hand, your father should be reminded of the commands of Allaah that encourage a husband to be kind-hearted and cordial with his wife as proved from the Prophet that he commanded: "Be kind to women (i.e. wives)." [Muslim]
Allaah knows best.
