Be careful that you do not leave the choice of music to someone who has yet to appreciate the need for keeping the volume at a moderate level.
كَمَا أَنَّ عَلَيْكَ ٱلِٱحْتِرَازَ لِئَلَّا تُوكِلَ مَسْؤُولِيَّةَ ٱخْتِيارِ ٱلْمُوسِيقَى إِلَى شَخْصٍ لَا يُدْرِكُ ٱلْحَاجَةَ إِلَى إِبْقَاءِ حَجْمِ ٱلصَّوْتِ مُعْتَدِلًا .‏
