فَذَٰلِكَ يَوْمَئِذٍۢ يَوْمٌ عَسِيرٌ
That Day will be a difficult day.
ذَرْنِى وَمَنْ خَلَقْتُ وَحِيدًۭا
Leave Me to him whom I created alone.
كَلَّآ ۖ إِنَّهُۥ كَانَ لِـَٔايَـٰتِنَا عَنِيدًۭا
By no means! He was stubborn towards Our revelations.
فَقَالَ إِنْ هَـٰذَآ إِلَّا سِحْرٌۭ يُؤْثَرُ
And said, “This is nothing but magic from the past.
إِنْ هَـٰذَآ إِلَّا قَوْلُ ٱلْبَشَرِ
This is nothing but the word of a mortal.”
وَمَآ أَدْرَىٰكَ مَا سَقَرُ
But what will explain to you what Saqar is?
وَمَا جَعَلْنَآ أَصْحَـٰبَ ٱلنَّارِ إِلَّا مَلَـٰٓئِكَةًۭ ۙ وَمَا جَعَلْنَا عِدَّتَهُمْ إِلَّا فِتْنَةًۭ لِّلَّذِينَ كَفَرُوا۟ لِيَسْتَيْقِنَ ٱلَّذِينَ أُوتُوا۟ ٱلْكِتَـٰبَ وَيَزْدَادَ ٱلَّذِينَ ءَامَنُوٓا۟ إِيمَـٰنًۭا ۙ وَلَا يَرْتَابَ ٱلَّذِينَ أُوتُوا۟ ٱلْكِتَـٰبَ وَٱلْمُؤْمِنُونَ ۙ وَلِيَقُولَ ٱلَّذِينَ فِى قُلُوبِهِم مَّرَضٌۭ وَٱلْكَـٰفِرُونَ مَاذَآ أَرَادَ ٱللَّهُ بِهَـٰذَا مَثَلًۭا ۚ كَذَٰلِكَ يُضِلُّ ٱللَّهُ مَن يَشَآءُ وَيَهْدِى مَن يَشَآءُ ۚ وَمَا يَعْلَمُ جُنُودَ رَبِّكَ إِلَّا هُوَ ۚ وَمَا هِىَ إِلَّا ذِكْرَىٰ لِلْبَشَرِ
We have appointed only angels to be wardens of the Fire, and caused their number to be a stumbling block for those who disbelieve; so that those given the Scripture may attain certainty; and those who believe may increase in faith; and those given the Scripture and the believers may not doubt; and those in whose hearts is sickness and the unbelievers may say, “What did God intend by this parable?” Thus God leads astray whom He wills, and guides whom He wills. None knows the soldiers of your Lord except He. This is nothing but a reminder for the mortals.
لِمَن شَآءَ مِنكُمْ أَن يَتَقَدَّمَ أَوْ يَتَأَخَّرَ
To whomever among you wishes to advance, or regress.
كُلُّ نَفْسٍۭ بِمَا كَسَبَتْ رَهِينَةٌ
Every soul is hostage to what it has earned.
قَالُوا۟ لَمْ نَكُ مِنَ ٱلْمُصَلِّينَ
They will say, “We were not of those who prayed.
وَكُنَّا نَخُوضُ مَعَ ٱلْخَآئِضِينَ
And we used to indulge with those who indulge.
وَكُنَّا نُكَذِّبُ بِيَوْمِ ٱلدِّينِ
And we used to deny the Day of Judgment.
فَمَا تَنفَعُهُمْ شَفَـٰعَةُ ٱلشَّـٰفِعِينَ
But the intercession of intercessors will not help them.
فَمَا لَهُمْ عَنِ ٱلتَّذْكِرَةِ مُعْرِضِينَ
Why are they turning away from the Reminder?
كَأَنَّهُمْ حُمُرٌۭ مُّسْتَنفِرَةٌۭ
As though they were panicked donkeys.
بَلْ يُرِيدُ كُلُّ ٱمْرِئٍۢ مِّنْهُمْ أَن يُؤْتَىٰ صُحُفًۭا مُّنَشَّرَةًۭ
Yet every one of them desires to be given scrolls unrolled.
كَلَّا ۖ بَل لَّا يَخَافُونَ ٱلْـَٔاخِرَةَ
No indeed! But they do not fear the Hereafter.
Summarized notes on Surah Al-Muddaththir
Muhammad (PBUH) was asked to rise and warn; to magnify God, to stay purified, and to not be driven by worldly gains. Last Day will be tough for disbelievers. They will be punished by God. Everyone is answerable to God. Those who don't pray, don't give alms, engage in vain disputes and deny Judgement Day will get Hell. No intercessors/mediators for them. Fear God. God forgives.

The Quran is clearly revelation from the One God, Who created all. The word Quran means recitation. Read about its compilation here - Islamweb.net. ExploreQuran.org displays Quran chapters in both, the actual compilation order (in printed copies), as well as a revelation order which might provide a different approach for exploring the Holy Quran.
