This list may be further extended but all these three tests of greatness are eminently satisfied to the highest degree in case of prophet Mohammad. Some illustrations of the last two have already been mentioned. The first is: Was the Prophet of Islam found to be of true metel by his contemporaries?
Historical records show that all the contemporaries of Mohammad both friends foes, acknowledged the sterling qualities, the spotless honesty, the noble virtues, the absolute sincerity and every trustworthiness of the apostle of Islam in all walks of life and in every sphere of human activity. Even the Jews and those who did not believe in his message, adopted him as the arbiter in their personal disputes by virtue of his perfect impartiality.
Even those who did not believe in his message were forced to say "O Mohammad, we do not call you a liar, but we deny him who has given you a book and inspired you with a message." They thought he was one possessed. They tried violence to cure him. But the best of them saw that a new light had dawned on him and they hastened him to seek the enlightenment.
It is a notable feature in the history of prophet of Islam that his nearest relation, his beloved cousin and his bosom friends, who know him most intimately, were not thoroughly imbued with the truth of his mission and were convinced of the genuineness of his divine inspiration.
If these men and women, noble, intelligent, educated and intimately acquainted with his private life had perceived the slightest signs of deception, fraud, earthliness, or lack of faith in him, Mohammad's moral hope of regeneration, spiritual awakening, and social reform would all have been foredoomed to a failure and whole edifice would have crumbled to pieces in a moment.
On the contrary, we find that devotion of his followers was such that he was voluntarily acknowledged as dictator of their lives. They braved for him persecutions and danger; they trusted, obeyed and honored him even in the most excruciating torture and severest mental agony caused by excommunication even unto death. Would this have been so, had they noticed the slightest backsliding in their master?
Read the history of the early converts to Islam, and every heart would melt at the sight of the brutal treatment of innocent Muslim men and women. Sumayya, an innocent women, is cruelly torn into pieces with spears.
