The unexpected death of his master, Saïd, was a great blow to Arabi's hopes. Under Ismaïl the favour shown to the fellah officers was withdrawn, and all preferment was once more given to the Circassians. Arabi found himself treated with scant courtesy by these, and was given only subordinate duties to perform in the transport service and semi-civilian posts. This threw him into the ranks of the discontented and made him more than ever the advocate of the rights of his own class. He was eloquent and able to expound his views in the sort of language his countrymen understood and appreciated, not very precise language perhaps, but illustrated with tropes and metaphors and texts from the Koran, which his Azhar education supplied. He thus exercised a considerable influence over those with whom he came in contact. During this period he came a good deal into the society of Europeans, especially at Alexandria, where he had been sent on business, not altogether military, connected with the Khedive's Daïra. His relations with these were friendly, and throughout his career he remained free from the least taint of fanatical intolerance in regard to Christians. On points of religion, though his practice was strict, he belonged to the largest and most liberal school of Mohammedan interpretation, and he was essentially a humanitarian in his ideas of the fraternity of nations and creeds.
