Readings from the Quran [16]: Who will Loose the Most

Say: 'Shall We announce to you those who have lost the most through [their] actions?'
Those whose effort led them astray during worldly life, while they reckoned they were producing something fine,
are the ones who have disbelieved in their Lord's signs and about meeting Him;
their actions will prove to be useless, and We shall set up no weighing-in for them on Resurrection Day.

Such will be their reward -Hell,
because of how they have disbelieved and taken My signs and My messengers for a laughingstock.

Those who believe and perform honorable deeds will have the gardens of Paradise as a lodging to live in for ever;
they will never seek any transfer from it.

Quran: 18: 103-109
