سنن ابن ماجه

It was narrated that Harithah bin Mudarrib said: “We came to Khabbab to visit him (when he was sick), and he said: ‘I have been sick for a long time, and were it not that I heard the Messenger of Allah (ﷺ) say: “Do not wish for death,” I would have wished for it.’ And he said: “A person will be rewarded for all his spending, except for (what he spends) on dust,” or he said, “on building.”
