Surat Al Anfal: (21-22)

{وَلاَ تَكُونُواْ كَالَّذِينَ قَالُوا سَمِعْنَا وَهُمْ لاَ يَسْمَعُونَ} [الأنفال: 21]

21- Do not be like polytheists and hypocrites who say with their tongues: "We heard" while they do not benefit with that hearing because they do not believe what they heard, so they look like as if they did not hear.

{إِنَّ شَرَّ الدَّوَابِّ عِندَ اللّهِ الصُّمُّ الْبُكْمُ الَّذِينَ لاَ يَعْقِلُونَ} [الأنفال: 22]

22- The worst creatures step on the ground are those who hear the truth but do not say it. So, they do not understand the words of Allah and do not benefit from because they did not use their minds and senses which Allah created for them as should to differentiate between the truth and falsehood, good and evil.
