He is the One Who accepts repentance from His servants and pardons ˹their˺ sins. And He knows whatever you do.He responds to those who believe and do good, and increases their reward out of His grace. As for the disbelievers, they will suffer a severe punishment.Quran: 42:25~26[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).
وَهُوَ ٱلَّذِی یَقۡبَلُ ٱلتَّوۡبَةَ عَنۡ عِبَادِهِۦ 
وَیَعۡفُوا۟ عَنِ ٱلسَّیِّءَاتِ وَیَعۡلَمُ مَا تَفۡعَلُونَ

وَیَسۡتَجِیبُ ٱلَّذِینَ ءَامَنُوا۟ وَعَمِلُوا۟ ٱلصَّـٰلِحَـٰتِ وَیَزِیدُهُم مِّن فَضۡلِهِۦۚ وَٱلۡكَـٰفِرُونَ لَهُمۡ 
عَذَابࣱ شَدِیدࣱ
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.
وہی ہے جو اپنے بندوں سے توبہ قبول کرتا ہے اور برائیوں سے درگزر کرتا ہے، 
حالانکہ تم لوگوں کے 
سب افعال کا اُ سے علم ہے 

وہ ایمان لانے والوں 
اور نیک عمل کرنے والوں کی دعا قبول کرتا ہے 
اور اپنے فضل سے ان کو 
اور زیادہ دیتا ہے رہے

انکار کرنے والے، 
تو ان کے لیے دردناک سزا ہے
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.
