لَوْ أَنزَلْنَا هَٰذَا ٱلْقُرْءَانَ عَلَىٰ جَبَلٍۢ لَّرَأَيْتَهُۥ خَٰشِعًۭا مُّتَصَدِّعًۭا مِّنْ خَشْيَةِ ٱللَّهِ ۚ وَتِلْكَ ٱلْأَمْثَٰلُ نَضْرِبُهَا لِلنَّاسِ لَعَلَّهُمْ يَتَفَكَّرُونَ
If We had caused this Qur'an to descend upon a mountain, thou (O Muhammad) verily hadst seen it humbled, rent asunder by the fear of Allah. Such similitudes coin We for mankind that haply they may reflect.
Surah Al-Hashr(59:21)

Chapter: At what age may a youth be listened to (i.e. quotation of the Hadith from a boy be acceptable)
Narrated Ibn `Abbas:
Once I came riding a she-ass and had (just) attained the age of puberty. Allah's Messenger (ﷺ) was offering the prayer at Mina. There was no wall in front of him and I passed in front of some of the row while they were offering their prayers. There I let the she-ass loose to graze and entered the row, and nobody objected to it.
