رَّسُولاً يَتْلُو عَلَيْكُمْ ايَاتِ اللَّهِ مُبَيِّنَاتٍ
...
A Messenger, who recites to you the Ayat of Allah containing clear explanations,
Some said that the Messenger is the subject of what is being sent (as a reminder) because the Messenger is the one that conveys the Dhikr.
Ibn Jarir said that what is correct is that the Messenger explains the Dhikr. This is why Allah the Exalted said here,
رَّسُولاً يَتْلُو عَلَيْكُمْ ايَاتِ اللَّهِ مُبَيِّنَاتٍ
(A Messenger, who recites to you the Ayat of Allah containing clear explanations),
meaning, plain and apparent.
The statement of Allah;
...
لِّيُخْرِجَ الَّذِينَ امَنُوا وَعَمِلُوا الصَّالِحَاتِ مِنَ الظُّلُمَاتِ إِلَى النُّورِ
...
that He may take out those who believe and do righteous good deeds, from the darkness to the light.
Allah's is like saying;
كِتَابٌ أَنزَلْنَـهُ إِلَيْكَ لِتُخْرِجَ النَّاسَ مِنَ الظُّلُمَـتِ إِلَى النُّورِ
A Book which We have revealed unto you in order that you might lead mankind out of darkness (14:1),
and,
اللَّهُ وَلِيُّ الَّذِينَ ءامَنُواْ يُخْرِجُهُم مِّنَ الظُّلُمَـتِ إِلَى النُّور
Allah is the Guardian of those who believe. He brings them out from darkness into light. (2:257)
meaning, out of the darkness of disbelief and ignorance into the light of faith and knowledge.
Allah the Exalted called the revelation that He has sent down, light, on account of the guidance that it brings.
Allah also called it Ruh, in that, it brings life to the hearts,
وَكَذَلِكَ أَوْحَيْنَأ إِلَيْكَ رُوحاً مِّنْ أَمْرِنَا مَا كُنتَ تَدْرِى مَا الْكِتَـبُ وَلاَ الاِيمَـنُ وَلَـكِن جَعَلْنَـهُ نُوراً نَّهْدِى بِهِ مَن نَّشَأءُ مِنْ عِبَادِنَا وَإِنَّكَ لَتَهْدِى إِلَى صِرَطٍ مُّسْتَقِيمٍ
And thus We have sent to you Ruh of our command. You knew not what is the book, nor what is faith But We have made it a light wherewith we guide whosoever of Our servants We will. And verily, you are indeed guiding to the straight path. (42:52)
Allah's statement,
...
وَمَن يُوْمِن بِاللَّهِ وَيَعْمَلْ صَالِحًا يُدْخِلْهُ جَنَّاتٍ تَجْرِي مِن تَحْتِهَا الاَْنْهَارُ خَالِدِينَ فِيهَا أَبَدًا
قَدْ أَحْسَنَ اللَّهُ لَهُ رِزْقًا
And whosoever believes in Allah and performs righteous good deeds, He will admit him into Gardens under which rivers flow, to dwell therein forever. Allah has indeed granted for him an excellent provision.
The same was explained several times before, and therefore, we do not need to repeat its explanation here.
All the thanks and praises are due to Allah.
