Surah 8. Al-Anfal
Ayah 20 - 23
٢٠. يَـٰٓأَيُّهَا ٱلَّذِينَ ءَامَنُوٓا۟ أَطِيعُوا۟ ٱللَّهَ وَرَسُولَهُۥ وَلَا تَوَلَّوْا۟ عَنْهُ وَأَنتُمْ تَسْمَعُونَ
٢١. وَلَا تَكُونُوا۟ كَٱلَّذِينَ قَالُوا۟ سَمِعْنَا وَهُمْ لَا يَسْمَعُونَ
٢٢. إِنَّ شَرَّ ٱلدَّوَآبِّ عِندَ ٱللَّهِ ٱلصُّمُّ ٱلْبُكْمُ ٱلَّذِينَ لَا يَعْقِلُونَ
٢٣. وَلَوْ عَلِمَ ٱللَّهُ فِيهِمْ خَيْرًا لَّأَسْمَعَهُمْ ۖ وَلَوْ أَسْمَعَهُمْ لَتَوَلَّوا۟ وَّهُم مُّعْرِضُونَ
[20-23] O Believers, obey Allah and His Messenger and do not turn away from the Message after hearing it. Do not be like those who said, "We have heard," but have not listened to it,16 for the vilest beasts in Allah's sight are those deaf, dumb people17 who do not use commonsense. Had Allah known any good in them, He would certainly have given them the power of hearing but if He had made them hear it (without perceiving any good in them), they would have turned away from it with disdain.18
16This exposes the attitude of the hypocrites, who heard the Truth with their ears, yet did not accept and believe in it: they professed to believe but did not obey the Commands.
17That is, "Those who do not listen to the Truth and do not utter it with their tongues, are deaf and dumb concerning the Truth."
18As those hypocrites had no love for the Truth and no desire to work in its cause, they would have turned their backs from the Battle at the first critical juncture, even if Allah had helped them to obey the Command and march to the battlefield. Thus their company would have proved to be harmful rather than useful.
