Imam Ali (PBUH) told Kumayl: O Kumayl! Those who compile wealth are dead even though they may be living, while the sages (who are endowed with knowledge) will remain as long as the world remains. Their bodies perish but their depictions will exist in the hearts.

Imam Ali (PBUH) said: The reward of a religious scholar is greater than the reward of a person who is fasting on days and establishes prayers during the night and fights in the Holy War for the sake of Allah. And, when a religious scholar dies, there will appear a gap in Islam which cannot be compensated except by a replacement of that (kind)

Imam Ridha (PBUH) said: Beware that surely a (true religious) jurist is he who pours forth his benediction unto people, saves them from their enemies, multiplies the blessings of Heaven for them, and earns the Pleasure of Allah the Exalted, for them (through guidance).

Imam Hasan al-Askari, (PBUH) said: The scholars of our followers (Shiah) are the guards of the bounds of Islam. Then, anyone of our followers who undertakes this (duty) is superior to the one who fights in the battle against the Romans, (because this one defends the theological bounds of our followers).

Washington wrote to King Charles of Spain requesting permission to purchase good quality breeding stock. In October of 1785, a ship docked in Boston harbor carrying a gift from King Charles for George Washington - - two fine jennies and a 4-year old Spanish jack named, appropriately, “Royal Gift’. That "royal gift" from the Spanish king is today credited with the development of the American mule which began a dynasty that “reshaped the very landscape of the country”.

George Washington played the major role in the development of the mule population in America. He recognized the value of the mule in agriculture and became the first American mule breeder.

Donkeys were already in America, as they came over with the early explorers, but they were quite small. Washington wished to breed the very best mules, but he faced a major obstacle - - the Spanish government at that time prohibited the acquisition or exportation of the famous Andalusian donkey.

Ten years after the conquest of the Aztecs, a shipment of three jacks and twelve jennies arrived from Cuba to begin breeding of mules in Mexico.

Female mules were preferred for riding while the males were preferred as pack animals throughout the Spanish Empire. Mules were not only used in the silver mines, but were very important along the Spanish frontier. Each outpost had to breed its own supply and every hacienda or mission kept at least one stud jack.

Mules were not as prevalent in Britain or America until the late 18th century. The chief demand for mules in Britain was for service in India and elsewhere abroad.

In 1495, Christopher Columbus brought four jack donkeys and two jenny donkeys to the New World, along with horses. These animals would be instrumental in producing mules for the Conquistadores in their exploration into the American mainland.

By the 18th century, the breeding of mules had become a flourishing industry in Spain, Italy, and France. For many years the French Province of Poitou was the primary European breeding center, with some 500,000 mules bred each year. Heavier draft mules were demanded for farm work and a local breed of stud donkey became most popular. Soon, Spain was at the forefront of the mule-breeding industry as Catalonia and Andalusia each developed a larger and stronger breed of donkey.

Mules were common in European cities long before the Renaissance. As early as 1294, Marco Polo reported on and praised the Turkoman mules he had seen in central Asia.

In Medieval Europe, when larger horses were being bred to carry heavily armored knights, mules were the preferred riding animal of gentlemen and clergy.

The Law of Moses (Leviticus 19:19) declared that the breeding of hybrid animals was forbidden. The Hebrews were not forbidden to use mules, but they had to purchase and import - - either from the Egyptians or the people of Togarmah (Armenia), who brought mule from the far north to Tyre for sale or barter.
