An-Najm (53:28)
وَمَا لَهُم بِهِۦ مِنۡ عِلۡمٍۖ إِن یَتَّبِعُونَ إِلَّا ٱلظَّنَّۖ وَإِنَّ ٱلظَّنَّ لَا یُغۡنِی مِنَ ٱلۡحَقِّ شَیۡـࣰٔا
And they have no knowledge thereof. They follow but a guess, and lo! a guess can never take the place of the truth.
— Mohammed Marmaduke William Pickthall
Wa maa lahum bihee min 'ilmin iny yattabi'oona illaz zanna wa innaz zanna laa yughnee minal haqqi shai'aa
