Read Ruku 429 of the Quran

وَإِنَّهُۥ لَعِلْمٌۭ لِّلسَّاعَةِ فَلَا تَمْتَرُنَّ بِهَا وَٱتَّبِعُونِ ۚ هَـٰذَا صِرَٰطٌۭ مُّسْتَقِيمٌۭ ﴿٦١﴾

And indeed, Jesus will be [a sign for] knowledge of the Hour, so be not in doubt of it, and follow Me. This is a straight path.

وَلَا يَصُدَّنَّكُمُ ٱلشَّيْطَـٰنُ ۖ إِنَّهُۥ لَكُمْ عَدُوٌّۭ مُّبِينٌۭ ﴿٦٢﴾

And never let Satan avert you. Indeed, he is to you a clear enemy.

وَلَمَّا جَآءَ عِيسَىٰ بِٱلْبَيِّنَـٰتِ قَالَ قَدْ جِئْتُكُم بِٱلْحِكْمَةِ وَلِأُبَيِّنَ لَكُم بَعْضَ ٱلَّذِى تَخْتَلِفُونَ فِيهِ ۖ فَٱتَّقُوا۟ ٱللَّهَ وَأَطِيعُونِ ﴿٦٣﴾

And when Jesus brought clear proofs, he said, "I have come to you with wisdom and to make clear to you some of that over which you differ, so fear Allah and obey me.

Indeed, Allah is my Lord and your Lord, so worship Him. This is a straight path."

فَٱخْتَلَفَ ٱلْأَحْزَابُ مِنۢ بَيْنِهِمْ ۖ فَوَيْلٌۭ لِّلَّذِينَ ظَلَمُوا۟ مِنْ عَذَابِ يَوْمٍ أَلِيمٍ ﴿٦٥﴾

But the denominations from among them differed [and separated], so woe to those who have wronged from the punishment of a painful Day.

هَلْ يَنظُرُونَ إِلَّا ٱلسَّاعَةَ أَن تَأْتِيَهُم بَغْتَةًۭ وَهُمْ لَا يَشْعُرُونَ ﴿٦٦﴾

Are they waiting except for the Hour to come upon them suddenly while they perceive not?

ٱلْأَخِلَّآءُ يَوْمَئِذٍۭ بَعْضُهُمْ لِبَعْضٍ عَدُوٌّ إِلَّا ٱلْمُتَّقِينَ ﴿٦٧﴾

Close friends, that Day, will be enemies to each other, except for the righteous
