On the authority of Abu Harayrah (may Allah be pleased with him) from the Prophet (ﷺ), who said:
Allah (mighty and sublime be He) said: Spend (on charity), O son of Adam, and I shall spend on you.
It was related by al-Bukhari (also by Muslim).
Imaam Ibnul Qayim (rahimahullah) stated:
"Time wasting is more serious than death because time wasting cuts you off from Allâh and the home of the afterlife, whereas death cuts you off from the worldly life and its people."
