Dear Friends! What is 1st April Fool, now read it carefully.
"In Spain, when Muslims went in hibernation and they were not visible, and had Taqqia, Spanish rulers planned to get them out for great slaughter. They brought few ships and announced that the decision is taken to let Muslims go away from Spain, unharmed. For which they had now kept few ships ready in Sea, and they will move by evening 31st March. So all Muslims started moving to ships, and no one was left in Spain, by the due date, with all their children, old and young, women and men, boys and girls, every soul then went to the ships, and were very happy to be liberated from non-Muslims, but AAH on on 1st April, the plan was implemented and the ships were drowned into the sea. All Muslims were killed, non could survive, and those who could were beheaded with sharp straight swords. It included kids, girls and boys, in all ages." Non-Muslims made fool of Muslims is 1st April Fool.

I never did after that, now upto you, what you like to do. Its a story that I heard, true or false, but a folk that was hurting to me and still hurts a lot.
