What is the meaning of "Al-Haram" mentioned in the Hadith: "Seek treatment, for Allah has not sent down a disease except that He has sent down a cure for it, save for one disease." They said: "O Messenger of Allah, what is it?" He said: "Al-Haram"?

The aforementioned Hadith is authentic, narrated by the compilers of the Sunan and others, and authenticated by Al-Albani. "Old age" (Al-Haram) means extreme old age and reaching its peak. The Prophet, peace and blessings be upon him, likened it to an ailment because death follows it.
