فَإِنْ أَعْرَضُوا فَمَا أَرْسَلْنَاكَ عَلَيْهِمْ حَفِيظًا إِنْ عَلَيْكَ إِلَّا الْبَلَاغُ وَإِنَّا إِذَا أَذَقْنَا الْإِنسَانَ مِنَّا رَحْمَةً فَرِحَ بِهَا وَإِن تُصِبْهُمْ سَيِّئَةٌ بِمَا قَدَّمَتْ أَيْدِيهِمْ فَإِنَّ الْإِنسَانَ كَفُورٌ
But if they disregard [your warnings], [keep in mind that] We have not sent you as their keeper. Your duty is only to communicate. Indeed when We let man taste Our mercy, he boasts about it; but should an ill visit him because of what his hands have sent ahead, then man is very ungrateful.
Agha Ali Puya Commentary
Commentary on Quran 42:48
[Pooya/Ali Commentary 42:48] Aqa Mahdi Puya says: Balagh means to deliver or convey the message which is the duty of a prophet. It also implies to guide those whom the message is conveyed to the end of the world which is the duty of a wali. Refer to Ali Imran: 68; Yunus: 10; Nahl: 53 and 54 and Rum: 36.
