"Would you deal with this camel?" ( a prank by noble sahabi Nuayman)

A man once came to the Prophet on a delegation and tethered his camel at the door of the Masjid. The Sahabah noticed that the camel had a large fat hump and their appetite for succulent tasty meat was stimulated. They turned to Nuayman and asked: "Would you deal with this camel?"
An-Nuayman understood what they meant. He got up and slaughtered the camel. The nomad Arab came out and realized what had happened when he saw people grilling, sharing out and eating meat. He shouted in distress: "Waa 'aqraah! Waa Naqataah! (O my camel!)"

The Prophet heard the commotion and came out. He learnt from the Sahabah what had happened and began searching for an-Nuayman but did not find him. Afraid of being blamed and punished, an-Nuayman had fled. The Prophet then followed his footprints. These led to a garden belonging to Danbaah the daughter of az-Zubayr, a cousin of the Prophet. He asked the companions where an-Nuayman was. Pointing to a nearby ditch, they said loudly so as not to alert an-Nuayman: "We haven't found him, O Messenger of God." An-Nuayman was found in the ditch covered with palm branches and leaves and emerged with dirt on his head, beard and face. He stood in the presence of the Prophet who took him by the head and dusted the dirt from his face while he chuckled with laughter. The companions joined in the mirth. The Prophet paid the price of the camel to its owner and they all joined in the feast.
The Prophet obviously regarded an-Nuayman's pranks for what they were light-hearted sallies that were meant to create some relief and laughter. 

The religion of Islam does not require people to disdain seemly laughter and levity and remain perpetually gloomy. An appropriate sense of humor is often a saving grace.
