18وَإِن تُكَذِّبوا فَقَد كَذَّبَ أُمَمٌ مِن قَبلِكُم ۖ وَما عَلَى الرَّسولِ إِلَّا البَلاغُ المُبينُ(Saheeh International)And if you [people] deny [the message] – already nations before you have denied. And there is not upon the Messenger except [the duty of] clear notification.1 Commentators have differed over this verse – whether it is a continuation of the words of Prophet Abraham or words of comfort given by Allāh to Prophet Muḥammad (ṣ), which according to context seems more likely.
