Qur'an, Al-Hadid, Surah 57:20
Beware, the life of this world is nothing but a pastime, a momentary delight. It is but empty bragging, a pursuit of wealth and children. It is like the vegetation that flourishes after rain and is a source of delight to the farmer; but soon it turns yellow and withers away, crumbling into worthless waste. But in the life to come an eternal contentment or a grievous suffering awaits you. The life of this world is only an illusion.
