After belief in One God, belief in the Last Day is the most emphasised doctrine mentioned in the Holy Qur’an. No other revealed book draws such a vivid picture of Life after Death as does the Holy Qur’an.
According to the Holy Qur’an, the entire universe will come to an end on the Day of Judgement. The dead will be resurrected and accounts will be taken of their deeds. People with good records will enter into heaven while those with bad records will be thrown into hell. According to the teachings of Islam, hell is a temporary abode while heaven is everlasting (it may be noted here that many Muslims believe that hell is also everlasting).
The Garden promised to the righteous has rivers of water that is not corrupted; and rivers of milk of which the taste changes not; and rivers of wine full of delight for those who drink; and rivers of pure honey. Thus paradise may be understood as having endless streams flowing with these things. Some people unfortunately misunderstand these things and take them literally. The water of life which a person, possessing insight, drinks spiritually in this life will be present overtly in the life to come. The spiritual milk which he drinks spiritually like a suckling babe in this world, will be seen openly in paradise. The wine of the love of God with which he was spiritual drunk in the world will be made manifest in paradise in streams. The honey of the sweetness of the faith, which one possessed of insight, swallowed spiritually in the world will be felt and observed in the shape of streams in paradise. In short, spiritual condition will be no longer hidden, but will become physically visible.
In the Holy Qur’an there are many signs of the coming of the Hour but its exact timing is known only to God. Following is a description of the Day of Judgement taken from Holy Qur’an, Surah Al-Qariah, Chapter 101.
The Great Calamity; What a Great Calamity!
And what should make thee know what the Great Calamity is?
The day when men will be like scattered moths;
And mountains will be like carded wool;
Then as for him whose scales are heavy,
He will have a pleasant life.
But as for him whose scales are light,
He will have hell as his resort. (101: 2-10)
