Imagine your mother. You had a mistake, your mom forgived you, is she forget this. I think she wish you not to do again. If you did again same mistake, I think she will forgive you again, but she strongly wish you not to do again. Prophet Mohammad saw a woman who was seeking something in a warplace after the battle. She was running to one side, she couldn't find anyting and she was running other side. Then she saw a litte child, she wrinkled him, she smelled him, she kissed him again and again. Prophet Mohammad pointed that woman to the friends. He asked them that do this woman thrown out this child to the fire. All together answered, no. She is a mother and she never throwns out her child to the fire. Prophet Mohammad told them that The God is more compassion with the people than mothers. Yes when god forgives, he wants to forget.
