A man borrowed money from his sister's children and could not repay it due to his poor financial situation. When he fell ill, they did not visit their sick uncle because they were angry with him and suspected that he had taken their money unlawfully. The sick man's sister conveyed their words for the sake of her brother so that he would be aware of his actions and not put himself in a position of suspicion and severing family ties. Is she sinful for doing this?
