Al An'am, 114 Ayah
6:114
أَفَغَيۡرَ ٱللَّهِ أَبۡتَغِي حَكَمٗا وَهُوَ ٱلَّذِيٓ أَنزَلَ إِلَيۡكُمُ ٱلۡكِتَٰبَ مُفَصَّلٗاۚ وَٱلَّذِينَ ءَاتَيۡنَٰهُمُ ٱلۡكِتَٰبَ يَعۡلَمُونَ أَنَّهُۥ مُنَزَّلٞ مِّن رَّبِّكَ بِٱلۡحَقِّۖ فَلَا تَكُونَنَّ مِنَ ٱلۡمُمۡتَرِينَ ١١٤
'Afaghayra Al-Lahi 'Abtaghī Ĥakamāan Wa Huwa Al-Ladhī 'Anzala 'Ilaykumu Al-Kitāba Mufaşşalāan Wa ۚ Al-Ladhīna 'Ātaynāhumu Al-Kitāba Ya`lamūna 'Annahu Munazzalun Min Rabbika Bil-Ĥaqqi ۖ Falā Takūnanna Mina Al-Mumtarīna
[Say], "Then is it other than Allah I should seek as judge while it is He who has revealed to you the Book explained in detail?" And those to whom We [previously] gave the Scripture know that it is sent down from your Lord in truth, so never be among the doubters.
