Mullah Nasruddin had a beautiful daughter, the desire of all the evil eyes of the men lived in his village. Everyone sought the hand of the fair maiden, but Mullah Nasruddin protected her from the ouside world, saving her for the wealthy young khan who lived just outside the village.
At last the young Khan came to ask for the hand of the beautiful maiden. Mullah Nasruddin drove a hard bargain and was to receive the highest bride-price ever bargained for in the entir region.
With the usual Muslim regard for ceremony, Mullah Nasruddin insisted on a long waiting-period before the wedding vows could be taken. It seems that the young and beautiful daughter of Mullah Nasrudin had a mind and a body of her own. She fell in love with a young stalwart who lived near the well in the village, who constantly showered her with attention as she went to the nearby well to gather water in the morning and at dusk.
Her trips to get water began to take longer periods of time. Most people in the village know what was happening, but no one dared tell Mullah Nasruddin. The time for the wedding approached and the young, wealthy Khan came to collect his bride.
Mullah Nasruddin brought her to greet her bridegroom. Lo and behold! She was well pregnant by this time. The young, rich Khan was horrified, and turned on to Mullah Nasruddin, demanding to know why such a thing had occurred.
And when Mullah Nasruddin merely replied that such things are normal when people get married, the young, rich Khan stormed out of Mullah Nasruddin's compound, and said that he withdrew his offer of marriage to the young beautiful daughter of Mullah Nasruddin and therefore would expect a return on the down payment on the bride price.
Mullah Nasruddin, genuinely shocked, called after the young, rich Khan and the young Khan returned. "let us be sensible about this," pleaded Mullah Nasruddin. "Actually, I should double the bride price now that my daughter is truly pregnant and can give you a son."
The young Khan, even more horrified, stuttered and asked, "In the name of Allah, why?" Mullah Nasruddin calmly replied, "Why just last week I delivered a cow to a man to whom I had sold the cow several months before. In the interim period, the cow became pregnant, and when I delivered the cow, I demanded and received twice the original amount. Now what is so different between a cow and a daughter?"
