الَّذِيْنَ يَسْتَمِعُوْنَ الْقَوْلَ فَيَتَّبِعُوْنَ اَحْسَنَهٗ ۗ اُولٰۤىِٕكَ الَّذِيْنَ هَدٰىهُمُ اللّٰهُ وَاُولٰۤىِٕكَ هُمْ اُولُوا الْاَلْبَابِ ( الزمر: ١٨ )
Allazeena yastami'oonal qawla fayattabi'oona ahsanah; ulaaa'ikal lazeena hadaahumul laahu wa ulaaa'ika hum ulul albaab (az-Zumar 39:18)
Who listen to speech and follow the best of it. Those are the ones Allah has guided, and those are people of understanding. (Az-Zumar  : 18)

who listen to what is said, then, follow the best of it. Those are the ones whom Allah has guided, and those are the ones who possess understanding.
