What is required to benefit from a reminder
Two conditions, and either one is enough.
Say this
إِنَّ فِى ذَٰلِكَ لَذِكْرَىٰ لِمَن كَانَ لَهُۥ قَلْبٌ أَوْ أَلْقَى ٱلسَّمْعَ وَهُوَ شَهِيدٌ
Inna fī dhālika la-dhikrā li-man kāna lahu qalbun aw alqa-s-samʿa wa huwa shahīd.
“Indeed in that is a reminder for whoever has a heart or who listens while he is present [in mind].”
Recitation by Mishari Rashid al-Afasy, via Quran.com
Having a heart, or being fully present when listening. The verse allows for either.
