While the followers of the Prophet sought safety in foreign lands against the persecution of their people, he continued his warnings to the Quraish more strenuously than ever. Again they came to him with offers of riches and honor, which he firmly and utterly refused. But they mocked at him and urged him for miracles to prove his mission. He used to answer: "Allah has not sent me to work wonders; He has sent me to preach to you."
Thus disclaiming all power of wonder-working, the Prophet ever rested the truth of his divine mission upon his wise teachings. He addressed himself to the inner consciousness of man, to his common sense and to his own better judgment. Say (O Muhammad): 'lam only a human being like you. It is inspired in me that your Ilah (God) is One Ilah (God - Allah), therefore take the Straight Path to Him (with true Faith - Islamic Monotheism) and obedience to Him, and seek forgiveness of Him. And woe to Al-Mushrikeen: polytheists, pagans, idolaters, and disbelievers in the Oneness of Allah etc., those who worship others along with Allah or set up rivals or partners to Allah etc.. Surah 41: 6
