A monk prayed for sixty years in a room. After sixty years, he came out and was attracted to sin and did zina. He felt guilty so he went to pool to purify himself for prayer. A beggar came and requested him. He gave him in charity. During purifying, he died of heart attack. Angels of reward and angels of justice had a negotiation. Angels of justice said his zina nullifies his sixty years of worship. Angel of reward said but his near death charity has outweighed his zina. So, neither underestimate a once in a lifetime sin nor a small near death virtue.
