Ud'u ilaa sabeeli Rabbika bilhikmati walmaw 'izatil hasanati wa jaadilhum billatee hiya ahsan; inna Rabbaka huwa a'almu biman dalla 'an sabeelihee wa Huwa a'lamu bilmuhtadeen
(O Prophet), call to the way of your Lord with wisdom and goodly exhortation, and reason with them in the best manner possible. Surely your Lord knows best who has strayed away from His path, and He also knows well those who are guided to the Right Way.
