The messengers are the ones who call towards the guide of Allah

An-Nahl (The Bees)

وَلَقَدْ بَعَثْنَا فِي كُلِّ أُمَّةٍ رَسُولًا أَنِ اُعْبُدُوا اللَّهَ وَاجْتَنِبُوا الطَّاغُوتَ فَمِنْهُمْ مَنْ هَدَى اللَّهُ وَمِنْهُمْ مَنْ حَقَّتْ عَلَيْهِ الضَّلَالَةُ فَسِيرُوا فِي الْأَرْضِ فَانْظُرُوا كَيْفَ كَانَ عَاقِبَةُ الْمُكَذِّبِينَ {٣٦}

Indeed, We sent to every community a messenger, [saying], “Worship Allah and shun false gods.” Among them were some whom Allah guided, while others were destined to stray. So travel through the land and see how was the end of the deniers!

إِنْ تَحْرِصْ عَلَى هُدَاهُمْ فَإِنَّ اللَّهَ لَا يَهْدِي مَنْ يُضِلُّ وَمَا لَهُمْ مِنْ نَاصِرِينَ {٣٧}

Even though you are keen to guide them, but Allah does not guide those whom He causes to stray, and they will have no helpers.

وَأَقْسَمُوا بِاللَّهِ جَهْدَ أَيْمَانِهِمْ لَا يَبْعَثُ اللَّهُ مَنْ يَمُوتُ بَلَى وَعْدًا عَلَيْهِ حَقًّا وَلَكِنَّ أَكْثَرَ النَّاسِ لَا يَعْلَمُونَ {٣٨}

They swear by Allah their solemn oaths that Allah will not resurrect those who die. Yes He will! It is a true promise upon Him, but most people do not know –

لِيُبَيِّنَ لَهُمُ الَّذِي يَخْتَلِفُونَ فِيهِ وَلِيَعْلَمَ الَّذِينَ كَفَرُوا أَنَّهُمْ كَانُوا كَاذِبِينَ {٣٩}

so that He may make clear to them that over which they differ, and so that the disbelievers may realize that they were liars.

إِنَّمَا قَوْلُنَا لِشَيْءٍ إِذَا أَرَدْنَاهُ أَنْ نَقُولَ لَهُ كُنْ فَيَكُونُ {٤٠}

When We intend something, We only say to it, “Be!”, and it is.
