The Prophet ﷺ said: Allah has sent down both the disease and the cure, and He has appointed a cure for every disease, so treat yourselves medically, but use nothing unlawful. (Using translation from Abū Dāʾūd 3874)
"إِنَّ اللهَ تَعَالى أَنْزَلَ الدَّاءَ والدَّوَاءَ، وَجَعَلَ لِكُلِّ دَاءٍ دَوَاءً. فَتَدَاوَوْا، ولا تَدَاوَوْا بحَرَامٍ" .
