Surah 75. Al-Qiyamah, Ayah 14

 Their organs will testify against them. See 41:19-24.

Cf. xxiv. 24, and n. 2976: "On the Day when their tongues, their hands, and their feet will bear witness against them as to their actions. " It is not what a man says about himself, or what others say of him, that determines judgment about him. It is what he is in himself. His own personality betrays him or commends him.
