Allah's statement,

﴿وَأَعْرِضْ عَنِ الْمُشْرِكِينَإِنَّا كَفَيْنَـكَ الْمُسْتَهْزِءِينَ ﴾

(and turn away from idolators. Truly, We will suffice you against the mockers.) meaning - convey that which has been revealed to you by your Lord, and do not pay attention to the idolators who want to turn you away from the signs of Allah.

﴿وَدُّواْ لَوْ تُدْهِنُ فَيُدْهِنُونَ ﴾

(They wish that you should compromise for them, so that they would compromise for you) (68:9). Do not fear them because Allah will suffice you against them, and He will protect you from them. This is like the Ayah:

﴿يَـأَيُّهَا الرَّسُولُ بَلِّغْ مَآ أُنزِلَ إِلَيْكَ مِن رَّبِّكَ وَإِن لَّمْ تَفْعَلْ فَمَا بَلَّغْتَ رِسَالَتَهُ وَاللَّهُ يَعْصِمُكَ مِنَ النَّاسِ﴾

(O Messenger! Proclaim that which has been revealed to you from your Lord. And if you do not do it, then you have not conveyed His Message. Allah will protect you from mankind.) ﴿5:67﴾ Muhammad bin Ishaq said: "The great ones of the mockers were five people, who were elders and noblemen among their people. From Bani Asad bin `Abd Al-`Uzza bin Qusayy there was Al-Aswad bin Al-Muttalib Abu Zam`ah. According to what I heard, the Messenger of Allah () had supplicated against him because of the pain and mockery he had suffered at his hands. He had said,

«اللَّهُمَّ أَعِمْ بَصَرَهُ، وَأَثْكِلْهُ وَلَدَه»

(O Allah, make him blind and take (the life of) his son.) From Bani Zahrah there was Al-Aswad bin `Abd Yaghuth bin Wahb bin `Abd Manaf bin Zahrah. From Bani Makhzum there was Al-Walid bin Al-Mughirah bin `Abdullah bin `Umar bin Makhzum. From Bani Sahm bin `Amr bin Husays bin Ka`b bin Lu'ayy there was Al-`As bin Wa'il bin Hisham bin Sa`id bin Sa`d. From Khuza`ah there was Al-Harith bin At-Talatilah bin `Amr bin Al-Harith bin `Abd `Amr bin Malkan. When their evil went to extremes and their mockery of the Messenger of Allah went too far, Allah revealed:

﴿فَاصْدَعْ بِمَا تُؤْمَرُ وَأَعْرِضْ عَنِ الْمُشْرِكِينَ - إِنَّا كَفَيْنَـكَ الْمُسْتَهْزِءِينَ - الَّذِينَ يَجْعَلُونَ مَعَ اللَّهِ إِلـهًا ءَاخَرَ فَسَوْفَ يَعْمَلُونَ ﴾

(Therefore openly proclaim that which you are commanded, and turn away from the idolators. Truly, We will suffice you against the mockers, who make another god along with Allah; but they will come to know.) Ibn Ishaq said: Yazid bin Ruman told me that `Urwah bin Az-Zubayr or one of the other scholars said that Jibril came to the Messenger of Allah when he was performing Tawaf around the House (the Ka`bah). He stood and the Messenger of Allah stood next to him. Al-Aswad Ibn Al-Mutalib passed by, and he threw a green leaf in his face, and he became blind. Al-Aswad bin `Abd Yaghuth passed by, and he pointed to his stomach, which swelled up and he died (of dropsy). Al-Walid bin Al-Mughirah passed by, and he pointed at a wound on lower of his ankle, which he got two years earlier when He once was trailing his garment and he passed by a man who was feathering his arrows. One of the arrows got caught in his garment and scratched his foot. It was an insignificant wound, but now it opened again and he died of it. Al-`As bin Wa'il passed by, and he pointed to the instep of his foot. He (Al-`As) set off on his donkey, heading for At-Ta'if. He rested by a thorny tree, a thorn pierced his foot and he died from it. Al-Harith bin At-Talatilah passed by and he pointed at his head. It filled with pus and killed him.''

﴿الَّذِينَ يَجْعَلُونَ مَعَ اللَّهِ إِلـهًا ءَاخَرَ فَسَوْفَ يَعْمَلُونَ ﴾

(Who make another god along with Allah; but they will come to know.) This is a strong warning and grave threat against those who have other deities along with Allah.
