39:18
ٱلَّذِينَ يَسْتَمِعُونَ ٱلْقَوْلَ فَيَتَّبِعُونَ أَحْسَنَهُۥٓ ۚ أُو۟لَـٰٓئِكَ ٱلَّذِينَ هَدَىٰهُمُ ٱللَّهُ ۖ وَأُو۟لَـٰٓئِكَ هُمْ أُو۟لُوا۟ ٱلْأَلْبَـٰبِ
alladhīna yastamiʿūna l-qawla fayattabiʿūna aḥsanahu ulāika alladhīna hadāhumu l-lahu wa-ulāika hum ulū l-albābi
who listen to what is said and follow what is best. These are the ones God has guided; these are the people of understanding.
Those who listen to the Word [good advice Lâ ilâha illallâh - (none has the right to be worshipped but Allâh) and Islâmic Monotheism] and follow the best thereof (i.e. worship Allâh Alone, repent to Him and avoid Tâghût) those are (the ones) whom Allâh has guided and those are men of understanding.
