If you try to use Islam as a means for them to give you financial support while they still resent you, you will not only increase their resentment for you but also their resentment of Islam.
What are my children’s rights upon me?
Thank you for your important question.
May Allah, Most High, cure you of all illnesses and grant you strength.
Allah, Most High, says:
“Your Lord has commanded that you should worship none but Him and that you be kind to your parents. If either or both of them reach old age with you, say no word that shows impatience with them, and do not be harsh with them, but speak to them respectfully” (Quran, 17:23)
We understand from this verse that it is obligatory upon children to be kind to their parents. Kindness means that they should show them mercy, patience and help them.
However, familial disputes are generally not resolved through the discussion of rights & responsibilities. They are solved through communication, respect, and acknowledgment of previous mistakes.
You mentioned that your children are upset with you due to how their mother was treated upon your taking of a second wife. You should open a dialogue with your children and explain the entire situation with them. Let them know what really happened and acknowledge any shortcomings you may have had.
Once you develop a good relationship with them, you can let them know that you are ill and in need of financial support.
If you are still married to your first wife, be sure to open the same dialogue with her. Don’t forget that Allah, Most High has commanded that a husband be just.
May Allah, Most High facilitate a beautiful bond of love and mercy between you and your family.
And Allah alone knows best,
