We make people fool on 1st April only to have some some fun and enjoyment but in reality it is the day when many of the muslims died.The story is when the muslims lived in Spain,some muslims were leaving Spain because of the danger from christians so they asked the christians for ships and christians said that they would reach safely to their destiny but on their way suddenly the ship started to burn because there were some chemicals and acids in it and the ship sank and all the muslims lost their lives so please dont celebrate this event.
