The reward of an evil deed is its equivalent. But whoever pardons and seeks reconciliation, then their reward is with Allah. He certainly does not like the wrongdoers.There is no blame on those who enforce justice after being wronged.Blame is only on those who wrong people and transgress in the land unjustly. It is they who will suffer a painful punishment.And whoever endures patiently and forgives—surely this is a resolve to aspire to.Quran 42:40~43Surah    ash-Shura (The Counsel)
The Surah takes its name from the Ayat,
وَالَّذِينَ اسْتَجَابُوا لِرَبِّهِمْ وَأَقَامُوا الصَّلَاةَ وَأَمْرُهُمْ شُورَىٰ بَيْنَهُمْ وَمِمَّا رَزَقْنَاهُمْ يُنفِقُونَ
“And those who have responded to their lord and established prayer and whose affair is [determined by] consultation among themselves, and from what We have provided them, they spend.” (42:38).

وَجَزَ ٰۤؤُا۟ سَیِّئَةࣲ سَیِّئَةࣱ مِّثۡلُهَاۖ فَمَنۡ عَفَا وَأَصۡلَحَ فَأَجۡرُهُۥ عَلَى ٱللَّهِۚ إِنَّهُۥ لَا یُحِبُّ ٱلظَّـٰلِمِینَ

وَلَمَنِ ٱنتَصَرَ بَعۡدَ ظُلۡمِهِۦ فَأُو۟لَـٰۤىِٕكَ مَا عَلَیۡهِم مِّن سَبِیلٍ

إِنَّمَا ٱلسَّبِیلُ عَلَى ٱلَّذِینَ یَظۡلِمُونَ ٱلنَّاسَ وَیَبۡغُونَ فِی ٱلۡأَرۡضِ بِغَیۡرِ ٱلۡحَقِّۚ أُو۟لَـٰۤىِٕكَ لَهُمۡ عَذَابٌ أَلِیمࣱ

وَلَمَن صَبَرَ وَغَفَرَ إِنَّ ذَ ٰلِكَ لَمِنۡ عَزۡمِ ٱلۡأُمُورِ
The Surah emphasizes that the message of the Qur’an is from Allah Who revealed similar messages to other Prophets and Messengers. The religion of Allah has been the same throughout history.
If Allah wanted He would have made all people into one Ummah, but He has given freedom to people to make their own choice by their free will.
Allah will judge all people on the Day of Judgment. In the Surah it is also mentioned that the followers of this message are those who avoid major sins and who manage their affairs with mutual consultation.
اور برائی کا بدلہ تو اسی طرح کی برائی ہے۔ 
مگر جو درگزر کرے 
اور (معاملے کو) درست کردے 
تو اس کا بدلہ خدا کے ذمے ہے۔ 
اس میں شک نہیں کہ وہ 
ظلم کرنے والوں کو پسند نہیں کرتا 

اور جس پر ظلم ہوا ہو 
اگر وہ اس کے بعد انتقام لے 
تو ایسے لوگوں پر کچھ الزام نہیں 

الزام تو ان لوگوں پر ہے جو لوگوں پر ظلم کرتے ہیں 
اور ملک میں ناحق فساد پھیلاتے ہیں۔

یہی لوگ ہیں جن کو 
تکلیف دینے والا عذاب ہوگا 

اور جو صبر کرے 
اور قصور معاف کردے 
تو یہ ہمت کے کام ہیں
Allah revealed His message to His Prophets. The purpose of revelation is to warn people about the Day of Judgment. Had Allah willed, He would have forced all people into one Ummah, but the wrong-does will see the consequences of their deeds.
The judgment is in the hand of Allah. He gave the same religion to all His Prophets. Muslims must invite people to Allah.
Allah deals justly with all people. Allah accepts the repentance. Allah’s mercy is manifest in the universe.
Believers should avoid sins, be patient, work with each other in consultation and practice forgiveness.
The Prophet guides to the right path, the path of Allah.
