WHO IS POOR?

One day the Prophet asked his dear companions whether they knew who was poor. They answered that poor was one who had no dirham or dinar (money). He said:

"In my Ummah, the poor is that man who would appear on the Day of the Judgment before Allah; he had offered prayer; he had paid Zakat; he had observed fast; but he would have abused somebody, he would have falsely accused someone; he would have unauthorisedly taken someone else's property; he would have murdered someone; would have hit somebody. All this virtues would be given to his victims. If his virtues are finished before his wicked deeds are finished, then the errors and sins of the victims would be given to him and he would be thrown into the Hell." --- (MUSLIM)

Such a man is really poor. His condition is like that trader who has goods worth one thousand rupees but he is a debtor for two thousand rupees. How can such a man be called rich?
