Allah says here:

كَذَلِكَ يَطْبَعُ اللَّهُ عَلَى قُلُوبِ الَّذِينَ لَا يَعْلَمُونَ ﴿٥٩﴾

فَاصْبِرْ إِنَّ وَعْدَ اللَّهِ حَقٌّ ...

Thus does Allah seal up the hearts of those who know not. So be patient. Verily, the promise of Allah is true;

meaning, `bear their stubborn opposition with patience, for Allah will fulfill His promise to grant you victory over them and cause you and those who follow you to prevail in this world and in the Hereafter.'

... وَلَا يَسْتَخِفَّنَّكَ الَّذِينَ لَا يُوقِنُونَ ﴿٦٠﴾

and let not those who have no certainty of faith discourage you (from conveying Allah's Message).

`Remain steadfast in the mission with which Allah has sent you, for it is truth in which there is no doubt. Do not turn away from it, for nowhere else is there truth which is to be followed; the truth rests exclusively in the Message with which you have been sent.'

Reports concerning the Virtues of this Surah and that it is recommended to recite it during Fajr

Imam Ahmad recorded from a man among the Companions of the Prophet that the Messenger of Allah led them in Fajr prayer and recited Ar-Rum in the prayer, but he became confused in his recitation.

He said:

إِنَّهُ يَلْبِسُ عَلَيْنَا الْقُرْآنَ، فَإِنَّ أَقْوَامًا مِنْكُمْ يُصَلُّونَ مَعَنَا لَا يُحْسِنُونَ الْوُضُوءَ، فَمَنْ شَهِدَ مِنْكُمُ الصَّلَاةَ مَعَنَا فَلْيُحْسِنِ الْوُضُوء

We have become confused in our recitation of Qur'an, because some people among you are praying with us but they have not performed Wudu' properly. Whoever attends the prayer with us, let him perform Wudu' properly.

This has a Hasan chain of narration, the text itself is Hasan.

It contains amazing information, that the Prophet was affected by the faulty Wudu' of some of those whom he was leading in prayer. This indicates that the prayer of the person who is praying in the congregation is connected to the prayer of the Imam.

This is the end of the Tafsir of Surah Al-Rum. Allah's is the praise and thanks.
