and Allah said "And proclaim the pilgramage among men; they will come to thee on foot and on every kind of camel. Lean on account of Journeys through deep and distant mountain highways" Surah 22 ~ Al Hajj Part 27
Persecution by the Quraish grew fiercer every day and the sufferings of the Prophet's disciples became unbearable. He had heard of the righteousness, tolerance, and hospitality of the neighboring Christian King of Abyssinia . He recommended such of his companions who were without protection to seek refuge in the kingdom of that pious king, Al Najashi (Negus). Some fifteen of the unprotected adherents of Islam promptly availed themselves of the advice and sailed to Abyssinia . Here they met with a very kind reception from the Negus. This is called the first hijrah (migration) in the history of Islam and occurred in the fifth year of the Prophet Muhammad's mission, A.D. 615. These emigrants were soon followed by many of their fellow sufferers, until the number reached eighty-three men and eighteen women.
The hostile Quraish, furious at the escape of their victims, sent deputies to the king of Abyssinia to request him to give up deliver the refugees, so that they might be put to death for adjuring their old religion and embracing a new one. The king summoned the poor fugitives and inquired of them what was the religion, which they had adopted in preference to their old faith. Ja'far, son of Abu Talib and brother of Ali, acted as spokesman for the exiles. He spoke thus: "O king, we were plunged in the depth of ignorance and barbarism, we adored idols, we lived in unchastity, and we ate dead bodies, and we spoke abomination, we disregarded every feeling of humanity and sense of duty towards our neighbors, and we knew no law but that of the strong, when Allah raised among us a man, of whose birth, truthfulness, honesty, and purity we were aware. He called us to profess the Unity of Allah and taught us to associate nothing with Him; he forbade us the worship of idols and enjoined us to speak the truth, to be faithful to our trusts, to be merciful, and to regard the rights of neighbors; he forbade us to speak evil of the worship of Allah and not to return to the worship of idols of woos and stone and to abstain from evil, to offer prayers, to give alms, to observe the fast. We have believed in him, we have accepted his teachings and his injunctions to worship Allah alone and to associate nothing with Him. Hence our people have persecuted us, trying to make us forego the worship of Allah and return to the worship of idols of wood and stone and other abominations. They have tortured us and injured us until, finding no safety among them, we have come to your kingdom trusting you will give us protection against their persecution."
After hearing the above speech, the hospitable king ordered the deputies to return to their people in safety and not to interfere with their fugitives. Thus the emigrants passed the period of exile in peace and comfort.
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 judgement . Say (O Muhammad): "I am only a human being like you. It is inspired in me that your AIlah (God) is One AIlah (God- Allah), therefore take the Straight Path to Him (with true Faith) and obedience to Him and seek forgiveness of Him. And woe to Al Mushrikeen; (polytheists, pagans, idolaters, and disbelivers) in the Oneness of Allah etc., those who worship others along with Allah or set up rivals or partners to Allah etc. ( 41:6 Quran)
Despite all the exhortation of the Prophet, the Quraish persisted in asking him for a sign. They insisted that unless some sign be sent down to him from his Lord, they would not believe. The disbelievers used to ask: "Why has Muhammad not been sent with miracles like previous prophets?" T he Prophet replied: "Because miracles had proved inadequate to convince. Noah was sent with signs, and with what effect? Where was the lost tribe of Thamud? They had refused to receive the preaching of the Prophet Salih, unless he showed them a sign and caused the rock to bring forth a living camel. He did what they asked. In scorn they cut the camel's feet and then daring the prophet to fulfill his threats of judgment, were found dead in their beds the next morning, stricken by the angel of the Lord."
There are some seventeen places in the Quran, in which the Prophet Muhammad is challenged to work a sign, and he answered them all to the same or similar effect: Allah has the power of working miracles, and has not been believed; there were greater miracles in nature than any which could be wrought outside of it; and the Quran itself was a great, everlasting miracle. The Quran, the Prophet used to assert to the disbelievers, is a book of blessings which is a warning for the whole world; it is a complete guidance and explains everything necessary; it is a reminder of what is imprinted on human nature and is free from every discrepancy and from error and falsehood. It is a book of true guidance and a light to all.
