The Prophet (may Allah's peace and blessings be upon him) invoked humiliation and disgrace to the extent that it was as if he had put his nose in the dust - repeating this thrice. He was, thus, asked: O Messenger of Allah, who is this one against whom you supplicated? He (may Allah's peace and blessings be upon him) said: The one whose parents—one of them or both—reached old age in his life, and they were not a means of admitting him to Paradise given his unkindness and undutifulness towards them.
