It is reported that some people asked ‘Alî b. Abî Tâlib – Allâh be pleased with him – to describe this worldly life (the dunyâ). He said:
Do you want a long description or a brief one? They replied, “a brief one.” He said, “Its permissible things (halâl) [lead to] accounts being taken from you, and its forbidden things (harâm) [lead to the] Fire.
Ibn Abî Al-Dunyâ, Dham Al-Dunyâ article 17.
