﴿ لِّيَعْلَمَ أَن قَدْ أَبْلَغُوا۟ رِسَٰلَٰتِ رَبِّهِمْ وَأَحَاطَ بِمَا لَدَيْهِمْ وَأَحْصَىٰ كُلَّ شَىْءٍ عَدَدًۢا ﴾

“so as to make manifest that it is indeed [but] their Sustainer's messages that these [apostles] deliver: for it is He who encompasses [with His knowledge] all that they have [to say], just as He takes count, one by one, of everything [that exists].”

The messenger of Truth is apparently a common man. Therefore, the people who are affected by his call turn upon him. They forget that any action against him amounts to action against God Himself. And who can be successful by taking action against God?
