Sayyiduna Abdullah bin Mas'ud (may Allah be pleased with him) narrates that the Prophet (peace and blessings be upon him) said: "Allah Almighty has not sent down any disease without also sending down its remedy. Whoever comes to know it knows it, and whoever remains unaware of it remains unaware."
(Allamah al-Haythami says:) I say: Ibn Majah recorded this report, but he did not record these words: "Whoever comes to know it knows it, and whoever remains unaware of it remains unaware."
Ahmad and al-Tabarani recorded it. The narrators of al-Tabarani are thiqat (trustworthy).
