(Ad-Dukhan) 44 : 58
فَإِنَّمَا يَسَّرْنَاهُ بِلِسَانِكَ لَعَلَّهُمْ يَتَذَكَّرُونَ
Then We have made it very easy with your tongue, so that they may remind others in their heart’s language.
That means Adhikr is made very easy for reminding others in their heart’s language, as explained in verse 54:17. See explanation 15:9 and 32:4.
