The visitations occurred several times, and each time they were accompanied by violent physical effects upon Mohammed. 'He was angry if anyone looked upon him: his face was covered with foam, his eyes were closed and sometimes he roared like a camel.' Even the faithful Khadîjah began to have her fears. Demon possession is a common idea in the East. 'Could it be that her exemplary husband was the victim of the wrath of some genius of evil?' She consulted her cousin, Warakah, {37} the sage and _savant_. His answer was wholly satisfactory, for he exclaimed: 'Holy! holy! by Him in Whose hand Warakah's soul is, if thou has told me the truth, then the Greatest Namus (nomos=law) has come to him which also appeared to Moses, and he is the Prophet of this nation. Tell him to be content.' Still her fears were not allayed, and a test was proposed. She reasoned thus: 'If it is an evil spirit which visits my husband, it will not be ashamed in the presence of an unveiled woman, but if the spirit is good he will surely be too modest to remain.' So with elaborate ritual the test was laid. Mohammed was to summon her when next his visitant appeared, and she was to take off her veil; should the spirit depart, she would know him for a good spirit. The visitant fully vindicated himself, disappearing from Mohammed's sight at the appearance of an unveiled woman; he never was visible to Khadîjah, From that day onwards, through storm, and shine, darkness and light, contumely ridicule, and persecution, Khadîjah never doubted, never wavered in complete confidence in her husband and his message. {38} [Sidenote: Days of Darkness.] For Mohammed there were yet many searchings of heart. He found himself unable to summon his visitor, or to command hours of inspiration at his will. Three years, it is said, he waited for another revelation, staggering in uncertainty and doubt and darkness, driven sometimes to the brink of despair, saved from suicide once at least only by the intervention of his wife. Light seemed to struggle with darkness in his soul, but gradually certain grand verities stood out clear. 'God, the sole Creator, Ruler, Judge of men and angels; the hopeless wretchedness of his people sunk in darkness and idolatry; Heaven and hell, the Resurrection, Judgment, the Recompense of good and evil in the World to come.' We can gather something of the sombre realities he saw, and something of the conviction with which they came to him from some of the suras written at the time: 'THAT WHICH STRIKETH! WHAT IS IT WHICH STRIKETH? AND WHAT SHALL CERTIFY THEE WHAT THE STRIKING IS? THE DAY ON WHICH MANKIND SHALL BE LIKE MOTHS SCATTERED ABROAD, {39} AND THE MOUNTAINS LIKE WOOL OF DIVERS COLOURS CARDED; THEN, AS FOR HIM WHOSE BALANCES ARE HEAVY, HE SHALL ENTER INTO BLISS; AND AS FOR HIM WHOSE BALANCES ARE LIGHT, THE PIT SHALL BE HIS DWELLING-PLACE. AND WHAT SHALL CERTIFY THEE WHAT IS THE PIT? A RAGING FIRE!' [Sidenote: The One God.]
