Ibn Abbas said, "If it pleases you to know the ignorance of the Arabs, then read what comes after verse one hundred and thirty in Surah al-Anam, 'Lost indeed are those who have killed their children foolishly, without knowledge' up to His saying 'they have certainly gone astray and were not rightly guided'" [Anam 6:140].
إذا سرك أن تعلم جهل العرب، فاقرأ ما فوق الثلاثين ومئة في سورة الأنعام {قد خسر الذين قتلوا اولادهم سفها بغير علم} إلى قوله {قد ضلوا وما كانوا مهتدين}.
