Surah 103. Al-Asr, Ayah 2

If life be considered under the metaphor of a business bargain, man, by merely attending to his material gains, will lose. When he makes up his day's account in the afternoon, it will show a loss. It will only show profit if he has Faith, leads a good life, and contributes to social welfare by directing and encouraging other people on the Path of Truth and Constancy.
