When you think you could never learn it
Repeated four times in one sūrah, unchanged.
وَلَقَدْ يَسَّرْنَا ٱلْقُرْءَانَ لِلذِّكْرِ فَهَلْ مِن مُّدَّكِرٍ
Wa laqad yassarna-l-qur'āna li-dh-dhikr, fa-hal min muddakir.
“And We have certainly made the Qur’ān easy for remembrance, so is there any who will remember?”
