You can only warn him who follows the Reminder (the Quran), and fears the Most Beneficent (Allah) unseen. Bear you to such one the glad tidings of forgiveness, and a generous reward (i.e. Paradise).
Hakika wewe unamwonya mwenye kufuata ukumbusho, na akamcha Arrahman, Mwingi wa Rehema, kwa ghaibu. Basi mbashirie huyo msamaha na ujira mwema.
