The Repentance
فَسِيحُوا۟ فِى ٱلْأَرْضِ أَرْبَعَةَ أَشْهُرٍ وَٱعْلَمُوٓا۟ أَنَّكُمْ غَيْرُ مُعْجِزِى ٱللَّهِ ۙ وَأَنَّ ٱللَّهَ مُخْزِى ٱلْكَـٰفِرِينَ
So travel freely, [O disbelievers], throughout the land [during] four months but know that you cannot cause failure to Allah and that Allah will disgrace the disbelievers.
Nearby ayahs help place verse 9:2 in sequence and meaning.
بَرَآءَةٌ مِّنَ ٱللَّهِ وَرَسُولِهِۦٓ إِلَى ٱلَّذِينَ عَـٰهَدتُّم مِّنَ ٱلْمُشْرِكِينَ
[This is a declaration of] disassociation, from Allah and His Messenger, to those with whom you had made a treaty among the polytheists.
وَأَذَٰنٌ مِّنَ ٱللَّهِ وَرَسُولِهِۦٓ إِلَى ٱلنَّاسِ يَوْمَ ٱلْحَجِّ ٱلْأَكْبَرِ أَنَّ ٱللَّهَ بَرِىٓءٌ مِّنَ ٱلْمُشْرِكِينَ ۙ وَرَسُولُهُۥ ۚ فَإِن تُبْتُمْ فَهُوَ خَيْرٌ لَّكُمْ ۖ وَإِن تَوَلَّيْتُمْ فَٱعْلَمُوٓا۟ أَنَّكُمْ غَيْرُ مُعْجِزِى ٱللَّهِ ۗ وَبَشِّرِ ٱلَّذِينَ كَفَرُوا۟ بِعَذَابٍ أَلِيمٍ
And [it is] an announcement from Allah and His Messenger to the people on the day of the greater pilgrimage that Allah is disassociated from the disbelievers, and [so is] His Messenger. So if you repent, that is best for you; but if you turn away - then know that you will not cause failure to Allah. And give tidings to those who disbelieve of a painful punishment.
إِلَّا ٱلَّذِينَ عَـٰهَدتُّم مِّنَ ٱلْمُشْرِكِينَ ثُمَّ لَمْ يَنقُصُوكُمْ شَيْـًٔا وَلَمْ يُظَـٰهِرُوا۟ عَلَيْكُمْ أَحَدًا فَأَتِمُّوٓا۟ إِلَيْهِمْ عَهْدَهُمْ إِلَىٰ مُدَّتِهِمْ ۚ إِنَّ ٱللَّهَ يُحِبُّ ٱلْمُتَّقِينَ
Excepted are those with whom you made a treaty among the polytheists and then they have not been deficient toward you in anything or supported anyone against you; so complete for them their treaty until their term [has ended]. Indeed, Allah loves the righteous [who fear Him].
