وَمِنَ النَّاسِ مَنْ يُجَادِلُ فِي اللَّهِ بِغَيْرِ عِلْمٍ وَيَتَّبِعُ كُلَّ شَيْطَانٍ مَرِيدٍ ﴿۳﴾ كُتِبَ عَلَيْهِ أَنَّهُ مَنْ تَوَلَّاهُ فَأَنَّهُ يُضِلُّهُ وَيَهْدِيهِ إِلَى عَذَابِ السَّعِيرِ ﴿۴﴾

﴾3﴿ Wa minan naasi mai yujaadilu fil laahi bighairi 'ilminw wa yattabi'u kullaa shaitaanim mareed
﴾4﴿ Kutiba 'alaihi annahoo man tawallaahu fa annahoo yudilluhoo wa yahdeehi ilaa 'azaabis sa'eer

﴾3﴿ And among the people are those who argue about the oneness of Allah without knowledge, and they follow every rebellious devil
﴾4﴿ It has been decreed regarding one who follows him (Satan) that he will surely lead him astray and call him towards the punishment of the blazing Fire

[3] This warning is for those who deny tawḥīd and the Hereafter—who argue due to blind imitation, as indicated by the phrase (wa yattabiʿu kulla shayṭānin marīd).
The term shayṭān here refers to both human and jinn devils.
The commentator Ibn Kathīr has said that this describes the misguided innovators (ahl al-bidʿah), who openly turn away from the truth and follow falsehood.
They abandon what Allah the Exalted has revealed to the Messenger of Allah (May Allah bless him and give him peace), and instead follow misguided leaders who call toward innovations, desires, and their own opinions.
[4] The attribution of misguidance to Satan is due to his waswasah (whispers and suggestions).
The word (kutiba) refers to decreed predestination, or it can mean inevitability—that following him necessarily leads to misguidance.
(Tawallāhu) means he follows and imitates him in loyalty and obedience.
This explanation is from Ibn Kathīr.
