The harm and harrasment of the blasphemers against the Prophet increased after the death of his unclue Abu Talib, and his wife Khadija may Allah raise her rank. He was harmed personally along with his oppressed followers. Bilal the son of Rabah al-Habashiyy was tortured under the scorching heat of the sun and on the burning sand of the desert, they used to put rocks on his chest during the hot noon time. Sumayyah, the mother of ^Ammar and her husband Yasir died as martyrs for not submitting to the wishes of the blasphemers of Quraysh and persisting to not revoke their state of belief, ^Ammar, the son of Yasir was tortured too.
The Prophet and his Companions who believed in him endured and tolerated the wrong doings of the blasphemers by remaining steadfast to the path of Islam and acting in accordance with what is incumbent upon them of its rules. The blasphemers of the tribe of Quraysh opposed their call and harassed them in many ways. One day a person named ^Uqbah dared to come to the Prophet, sallallahu ^alayhi wa sallam, held him by his shoulders and strangled him so strongly until Abu Bakr came and stopped him and said: "Do you want to kill a man who says Allah is my Lord and who has provided proofs from Allah."
The Prophet, sallallahu ^alayhi wa sallam, advised his companions to migate to Al-Habashah (Abysiniah) where a just king- Christian at the time- presides and rules. Ten men and four women migrated at first and their number increased until it reached eighty three men an seveneteen women other than the children. To protect themselves against harm and to find comfort and justice under the king of Al-Habashah they migrated out of fear of sedition and for preserving their religiosity to Allah. This was the first Migration in Islam.
An-Najashiyy, The King of Abysinniah, received and treated them well and they enjoyed peace and safety as guests in his land. The blasphemers of Quraysh attempted to sway an-Najashiyy by offering him precious gifts but to no avail; he turn their attempt down when he heard from the companion blessed recitation of Qur'an regarding Prophet ^Isa and his mother Lady Maryam. He believed the Muslims and maintained his support of them and become himself a highly pious Muslim.
