The Corruption of Hearts

Al-Hasan al-Basri said, "The corruption of people's hearts is in six things - the first is that they sin with the hope of repentance; they seek knowledge but do not act upon it; if they do act upon it they are insincere in doing so; they eat the sustenance Allah has provided them but do not show gratitude for it; they are not content with the allotment (qisma) of Allah; and they bury their dead but do not take heed."
