The Grand Senussi preached a pure form of Islam and strict adherence to the laws of God and his Prophet Mohammed.
His teachings may perhaps be best illustrated by a passage from a letter to the people of Wajanga, in Wadai, the original of which I saw at Kufra and translated. The passage reads as follows:
We wish to ask you in the name of Islam to obey God and His Prophet. In his dear Book he says, praise be to him, “O ye, who are believers, obey God and obey the Prophet!” He also says, “He who obeys the Prophet has also obeyed God.” He also says, “He who obeys God and His Prophet has won a great victory.” He also says, “Those who obey God and the Prophet, they are with the prophets whom God has rewarded.”
We wish to ask you to obey what God and His Prophet have ordered; making the five prayers every day, keeping the month of Ramadan, giving tithes, making the haj to the sacred home of God [the pilgrimage to Mecca], and avoiding what God has forbidden—telling lies, slandering people behind their backs, taking unlawfully other people’s money, drinking wine, killing men unlawfully, bearing false witness, and the other crimes before God.
In following these you will gain everlasting good and endless benefits which can never be taken from you.
The principal concern of the founder of the Senussis was with the religious aspect of life. He did not set out to be a political leader or to grasp temporal power. He counseled austerity of life with the same enthusiasm with which he practised it. He taught no special theological doctrines and demanded acceptance of no particular dogmas. He cared much more for what his followers did than for any technicalities of belief. His only addition to the Moslem ritual was a single prayer, which he wrote and which the Senussis use, called the hezb. It is not opposed to anything taught by the older theologians, nor does it add anything to what is found in the Koran. It is simply expressed in different language. In the letter to the people of Wajanga, which I have quoted, another passage described his mission, which God had laid upon him, as that of “reminding the negligent, teaching the ignorant, and guiding him who has gone astray.”
He forbade all kinds of luxurious living to those who allied themselves with his brotherhood. The possession of gold and jewels was prohibited—except for the adornment of women—and the use of tobacco and coffee. He imposed no ritual and only demanded a return to the simplest form of Islam as it was found in the teaching of the Prophet. He was intolerant of any intercourse, not only with Christians and Jews, but with that part of the Moslem world which, in his conviction, had digressed from the original meaning of Islam.
In the year 1856 Sayed Ibn Ali founded at Jaghbub the zawia which eventually developed into the center of education and learning of the Senussi brotherhood. His choice of Jaghbub was not haphazard or accidental but a demonstration of his wisdom and practical sagacity. He conceived it to be of the first importance to reconcile the different tribes of the desert to each other and to bring peace among them. One more quotation from his letter illustrates this point:
We intend to make peace between you and the Arabs [the people of Wajanga to whom this letter is addressed are of the black race] who invade your territory and take your sons as slaves and your money. In so doing we shall be carrying out the injunction of God, who has said, “If two parties of believers come into conflict, make peace between them.” Also we shall be following his direction, “Fear God, make peace among those about you, and obey God and his Prophet if you are believers.”
