Prophet Muhammad (SAW) once told the story of a worshipper who lived in total isolation for 1000 years, doing nothing but worshipping Allah. When this man died, Allah ordered the angels to take him to Heaven by the Mercy of Allah. The man disagreed, stating that he should go to Heaven as a result of his own work, his 1000 years of worship. Allah then ordered His angels to settle the man's account.The angels put the worshipper's work on one scale of the balance and on the other they started by putting the blessing of eyesight. The scale carrying only the eyesight blessing was much heavier. The man then shouted, 'By your mercy, O Allah, by your mercy!'. Allah replied. 'Take my servant to Heaven by My Mercy.'
