A man worked hard to earn a huge amount of money that he put it in his back account. Whenever he was fined by his company for violating company rules, he used to write a check & pay that amount without keeping a check of how many checks he wrote. One day he was in an urgent need of money, he wrote a check & rushed towards the bank, but the check bounced as there was no money left in his account. He was shocked, couldn't believe it, till he was shown the complete bank statement.
The prophet (sallallahu aleihi wasallam) asked suhabas, "Do you know who is the bankrupt?" They replied " The one who has neither money nor property" He (sallallahu aleihi wasallam) said, " The real bankrupt of my ummah would be he who would come on the day of resurrection with many prayers, fasting & sadaqah; but he will find himself bankrupt on that day as he will have exhausted the funds of virtues because he reviled others, brought calumny against others, unlawfully devoured other's wealth, shed blood & beat others. So his virtues would be credited to the account of those who suffered at his hand. If his good deeds fall short to clear the account, their sins would be put in his account & he would be thrown in the hell fire "
