The story of humor Rasulullah

One day there was a grandmother who asked the Prophet SAW, "O Messenger of Allah, can I go to heaven?"
Prophet Muhammad SAW replied, "In heaven there is no parent."
Hearing the answer, the grandmother was naturally hit and very sad. But his disappointment did not last long. Rasulullah SAW again said, "In heaven who live only those who are young. The old man in the world will be young again while he is in heaven. "
Hadith scholars, judging the humor of this Prophet, besides giving birth smile, also bring the good news. Especially for the elderly. Intended for the elderly continue to improve their faith and charity to Allah SWT.
At other times, Rasulullah SAW also joked with his best friend, Anas bin Malik. He called Anas with the call, "O Two Owners of Ears!"
Of course this is the right humor and not off track. Anas bin Malik must have two ears, not four ears.
Humor and how to joke Rasulullah SAW never get out of control. What he does, never violates decency and no harm.
