the tow brothers, an Islamic tale

THERE were once two brothers who Jointly farmed a field, and always shared its yield.
One day one of them woke up in the night and thought: "My brother is married and has children. Because of this he has anxieties and expenses which are not mine. So I will go and move some sacks from my share into his storeroom, which is only fair. I shall do this under cover of night, so that he may not, from his generosity, dispute with my about it.
He moved the sacks, and went back to bed.
Soon afterwards the other brother woke up and thought to himself: " It is not fair that I should have half of all the com in our field.
My brother, who is unmarried, lacks my pleasures in having a family, and I shall therefore try to compensate a little by moving some of my com into his storeroom.'
So saying, he did so.
The next morning, each eas amazed he still had the same number of sacks in his storeroom, and afterwards neither could understand why, year after year, the number of sacks remained the same even when each of them shifted some by stealth.
