The Law of Moses (Leviticus 19:19) declared that the breeding of hybrid animals was forbidden.

Imam Ali (PBUH) said: When the utterance of the wise is to the point, it serves as a remedy, but if it is wrong it proves like an illness.

Imam al-Baqir (PBUH) said: When confronting a sage, try to be more inquisitive than talkative, and learn how to listen well as much as you learn how to speak well, and do not interrupt the statement of anyone.

The Holy Prophet (peace be upon him and his progeny) said: There are two groups of my Ummah that when they are pious, my Ummah will be upright and when they are immoral my Ummah will be corrupt. The Messenger of Allah (S) was asked who they were, and he answered: The religious scholars and rulers.

Imam Al-Ridha (PBUH) said: May the Mercy of Allah be upon the servant who keeps alive our commandment. Then the person attending the Imam asked him how their commandment could be kept alive and he replied: He (can) learn our knowledge and teach it to people. In fact, if people knew (the merits and) the goodness of our statements, surely they would follow us.

When Hannibal crossed the Alps in 216 BC, he had mules with him as well as elephants. He may even have ridden a mule in the rough terrain, where elephants could not easily maneuver.

The Holy Prophet (peace be upon him and his progeny) said: Verily, what will continue to reach a believer, after his death, from amongst his actions and good deeds are: the knowledge which he taught and spread, the righteous child whom he left behind, and the Holy script which he delivered as heritage (transcribed, and made available).

The Holy Prophet (Peace be upon him and his progeny) said: Someone who possesses knowledge on a subject but conceals it when he is asked will be bridled with reins of fire.

To keep the baggage trains from becoming too large, Marius had each man carry as much of his own equipment as he could, including his own armor, weapons and 15 days rations or about 50–60 pounds of load total. To make this easier, he issued each legionary a forked stick to carry his load on his shoulders. The soldiers became known as “Marius Mules”, (muli mariani in Latin) due to the amount of gear they had to carry themselves, a tribute to the mules physical stamina.]
