After Rasulullah (sallallahu ‘alaihi wasallam) began to openly proclaim tauheed and invite to Islam, most of the people of Makkah Mukarramah became his enemies. However, there were some people who had reached the limits in their hostility and enmity for Rasulullah (sallallahu ‘alaihi wasallam).
Some of these people were:
Abu Jahal bin Hishaam, Abu Lahab bin ‘Abdil Muttalib, Aswad bin ‘Abd-e-Yaghooth, Haarith bin Qays, Waleed bin Mugheerah, Umayyah bin Khalaf and Ubayy bin Khalaf (the sons of Khalaf), Abu Qays bin Faakihah, ‘Aas bin Waa’il, Nadhr bin Haarith, Munabbih bin Hajjaaj, Zuhair bin Abi Umayyah, Saa’ib bin Saifi, Aswad bin ‘Abdil Asad, ‘Aas bin Sa‘eed, ‘Aas bin Haashim, ‘Uqbah bin Abi Mu‘ait, Ibnul Asdaa Hakam bin ‘Aas and ‘Adiyy bin Hamraa’.
Most of these people were the neighbours of Rasulullah (sallallahu ‘alaihi wasallam) and men of high standing in society. They remained diligent and zealous in their hostility against Rasulullah (sallallahu ‘alaihi wasallam) and night and day, they made this their main mission. Abu Jahal, Abu Lahab and ‘Uqbah bin Abi Mu‘ait were at the forefront from all these enemies.
It is the system of Allah Ta‘ala that when he creates something, he also creates its opposite. Allah Ta‘ala states:
وَ مِنۡ کُلِّ شَیۡءٍ خَلَقۡنَا زَوۡجَیۡنِ لَعَلَّکُمۡ تَذَکَّرُوۡنَ
And from everything We have created pairs so that you may comprehend (the perfection of the Creator). (Surah Zaariyaat v. 49)
Hence, just as there is a Musa for every Fir‘aun, there must be a Fir‘aun for every Musa. Nevertheless, since things may be understood and recognized by viewing their opposites, we will next present a brief outline of each of the arch-enemies of Rasulullah (sallallahu ‘alaihi wasallam).
