I believe that not all lies are harmful. I listened to a story on radio how a woman brought unity back to her two children. Before the wise intervention of the mother, both sons were having serious disagreement between themselves. One of them lives abroad, while the other lives in their homeland. Due to the disagreement, the one living abroad stopped sending money to his brother but continued to send the mother some money. Noticing this, the mother decided to give some of her share to the other brother lying that it was from his brother living abroad. The grateful brother called his brother living abroad and showered praises on him, saying that, despite their feud, he still had it in his mind to send him money. The one living abroad was shocked because he never sent any money to him. Later on he called his mother and the mother told him that she had to lie to both of them in order to bring truce.
