مَا جَعَلَ ٱللَّهُ مِنۢ بَحِيرَةٍۢ وَلَا سَآئِبَةٍۢ وَلَا وَصِيلَةٍۢ وَلَا حَامٍۢ ۙ وَلَٰكِنَّ ٱلَّذِينَ كَفَرُوا۟ يَفْتَرُونَ عَلَى ٱللَّهِ ٱلْكَذِبَ ۖ وَأَكْثَرُهُمْ لَا يَعْقِلُونَ
Allah hath not appointed anything in the nature of a Bahirah or a Sa'ibah or a Wasilah or a Hami, but those who disbelieve invent a lie against Allah. Most of them have no sense.
