Surah Ya-Seen Ayah #11 Translated in English
إِنَّمَا تُنْذِرُ مَنِ اتَّبَعَ الذِّكْرَ وَخَشِيَ الرَّحْمَٰنَ بِالْغَيْبِ ۖ فَبَشِّرْهُ بِمَغْفِرَةٍ وَأَجْرٍ كَرِيمٍ
You can only warn one who follows the message and fears the Most Merciful unseen. So give him good tidings of forgiveness and noble reward.
