י"ב He asked, "Why does a donkey urinate on the urine of its fellow and smell its excrement?" He replied, "When the Holy One, blessed be He, created every creature, the donkey said to the horse and the mule, 'Every creature has its own benefit, and we toil from generation to generation without any benefit.' They prayed to their Creator to grant them some benefit, but their prayers were not answered. The Holy One said to them, 'When the time comes that your urine will flow like rivers and your excrement will smell like perfumes, then I will give you your reward.' Therefore, they smell and urinate on each other's waste."
