Abu ad-Dardaa (radiallaahu anhu) said:

“Everyone falls short of his wisdom and knowledge sometimes. If this life brought him an increase in money, he becomes happy and elated. Meanwhile, the nights and the days keep decreasing his life term, but he does not become sad on account of this decrease. *What good will the increases in wealth bring, when the life-term is ever decreasing?*”
