Is it permissible to sign a DNR (Do Not Resuscitate) document for a female child suffering from an incurable genetic brain disease, who is unresponsive to treatments, and whose health condition is deteriorating, based on the doctors' recommendation that this is the best option to alleviate her suffering?

Signing a "Do Not Resuscitate" (DNR) order is permissible only in specific cases clarified by scholars, which are: if the patient arrives at the hospital deceased, or if their condition is unsuitable for resuscitation, or if their illness is incurable and death is certain, or in a state of mental disability or torpor coupled with a chronic illness, or an irreversible brain injury, or if cardiopulmonary resuscitation is futile. In all these cases, a report from three trustworthy, specialized doctors is required. Furthermore, a person is considered legally dead if their heart and breathing have completely and irreversibly ceased, or if all functions of their brain have permanently shut down and begun to decompose, and doctors have determined that this is irreversible. In such a case, it is permissible to remove life support. Caution must be exercised to avoid rushing this decision.
