Haritha reports: I went to visit Khabbab (may Allah be pleased with him) when he was ill. He had cauterized his body. When he saw me, he said: I do not think anyone has suffered as much pain as I have. During the blessed era of the Prophet (peace be upon him), I could not get even a single dirham, and now in one corner of my house, forty thousand dirhams are buried. If I had not heard the Prophet (peace be upon him) say, "None of you should wish for death," I would certainly have wished for it.
