Silsilah as-Sahihah 283 — Cursing time is forbidden

Abu Huraira (may Allah be pleased with him) narrates that the Messenger of Allah (peace and blessings be upon him) said: "Do not revile time, for Allah, the Exalted, has said: I am time; I alternate the days and nights, and I cause them to wear out, and I bring kings one after another."
