Someone went to the Prophet Mohammed and asked him, "Prophet, you said there is a great debt to be paid to one's mother. Suppose that I gave my mother all that I have earned, would that pay her back?" The Prophet said, "No, not in the least. If you served her your whole life, even then you could not pay the debt of what she has done for you in one day. She brought you up with the thought always in her mind that even when she was gone you would live; she has not only given her service and heart and love to you, but also her life. That you will live after her, that has been all her thought. And what is your thought? If you are a kind and good person your thought is, 'So long as my poor mother is living, I will take care of her to the end; one day she will die, and then I shall be free.' It is a different thought from her thought."
