﴿ قُلْ أَرَءَيْتُم مَّآ أَنزَلَ ٱللَّهُ لَكُم مِّن رِّزْقٍۢ فَجَعَلْتُم مِّنْهُ حَرَامًۭا وَحَلَٰلًۭا قُلْ ءَآللَّهُ أَذِنَ لَكُمْ ۖ أَمْ عَلَى ٱللَّهِ تَفْتَرُونَ ﴾

“Say: "Have you ever considered all the means of sustenance which God has bestowed upon you from on high -and which you thereupon divide into 'things forbidden' and 'things lawful? Say: "Has God given you leave [to do this] -or do you, perchance, attribute your own guesswork to God?"”
