Surah Al-Hajj — Ayah 8 (22:8)
وَمِنَ ٱلنَّاسِ مَن يُجَٰدِلُ فِي ٱللَّهِ بِغَيۡرِ عِلۡمٖ وَلَا هُدٗى وَلَا كِتَٰبٖ مُّنِيرٖ ٨
English translation (Saheeh International)
And of the people is he who disputes about Allāh without knowledge or guidance or an enlightening book [from Him],
Brief commentary
Among the disbelievers is he who argues regarding the oneness of Allah and regarding His sending His Messenger with guidance, without any proof from sound reasoning or clear sound texts, but solely due to his desires.
