Read Ruku 169 of the Quran

ٱلتَّـٰٓئِبُونَ ٱلْعَـٰبِدُونَ ٱلْحَـٰمِدُونَ ٱلسَّـٰٓئِحُونَ ٱلرَّٰكِعُونَ ٱلسَّـٰجِدُونَ ٱلْـَٔامِرُونَ بِٱلْمَعْرُوفِ وَٱلنَّاهُونَ عَنِ ٱلْمُنكَرِ وَٱلْحَـٰفِظُونَ لِحُدُودِ ٱللَّهِ ۗ وَبَشِّرِ ٱلْمُؤْمِنِينَ ﴿١١٢﴾

[Such believers are] the repentant, the worshippers, the praisers [of Allah], the travelers [for His cause], those who bow and prostrate [in prayer], those who enjoin what is right and forbid what is wrong, and those who observe the limits [set by] Allah. And give good tidings to the believers.

مَا كَانَ لِلنَّبِىِّ وَٱلَّذِينَ ءَامَنُوٓا۟ أَن يَسْتَغْفِرُوا۟ لِلْمُشْرِكِينَ وَلَوْ كَانُوٓا۟ أُو۟لِى قُرْبَىٰ مِنۢ بَعْدِ مَا تَبَيَّنَ لَهُمْ أَنَّهُمْ أَصْحَـٰبُ ٱلْجَحِيمِ ﴿١١٣﴾

It is not for the Prophet and those who have believed to ask forgiveness for the polytheists, even if they were relatives, after it has become clear to them that they are companions of Hellfire.

وَمَا كَانَ ٱسْتِغْفَارُ إِبْرَٰهِيمَ لِأَبِيهِ إِلَّا عَن مَّوْعِدَةٍۢ وَعَدَهَآ إِيَّاهُ فَلَمَّا تَبَيَّنَ لَهُۥٓ أَنَّهُۥ عَدُوٌّۭ لِّلَّهِ تَبَرَّأَ مِنْهُ ۚ إِنَّ إِبْرَٰهِيمَ لَأَوَّٰهٌ حَلِيمٌۭ ﴿١١٤﴾

And the request of forgiveness of Abraham for his father was only because of a promise he had made to him. But when it became apparent to Abraham that his father was an enemy to Allah, he disassociated himself from him. Indeed was Abraham compassionate and patient.

وَمَا كَانَ ٱللَّهُ لِيُضِلَّ قَوْمًۢا بَعْدَ إِذْ هَدَىٰهُمْ حَتَّىٰ يُبَيِّنَ لَهُم مَّا يَتَّقُونَ ۚ إِنَّ ٱللَّهَ بِكُلِّ شَىْءٍ عَلِيمٌ ﴿١١٥﴾

And Allah would not let a people stray after He has guided them until He makes clear to them what they should avoid. Indeed, Allah is Knowing of all things.

إِنَّ ٱللَّهَ لَهُۥ مُلْكُ ٱلسَّمَـٰوَٰتِ وَٱلْأَرْضِ ۖ يُحْىِۦ وَيُمِيتُ ۚ وَمَا لَكُم مِّن دُونِ ٱللَّهِ مِن وَلِىٍّۢ وَلَا نَصِيرٍۢ ﴿١١٦﴾

Indeed, to Allah belongs the dominion of the heavens and the earth; He gives life and causes death. And you have not besides Allah any protector or any helper.

لَّقَد تَّابَ ٱللَّهُ عَلَى ٱلنَّبِىِّ وَٱلْمُهَـٰجِرِينَ وَٱلْأَنصَارِ ٱلَّذِينَ ٱتَّبَعُوهُ فِى سَاعَةِ ٱلْعُسْرَةِ مِنۢ بَعْدِ مَا كَادَ يَزِيغُ قُلُوبُ فَرِيقٍۢ مِّنْهُمْ ثُمَّ تَابَ عَلَيْهِمْ ۚ إِنَّهُۥ بِهِمْ رَءُوفٌۭ رَّحِيمٌۭ ﴿١١٧﴾

Allah has already forgiven the Prophet and the Muhajireen and the Ansar who followed him in the hour of difficulty after the hearts of a party of them had almost inclined [to doubt], and then He forgave them. Indeed, He was to them Kind and Merciful.

وَعَلَى ٱلثَّلَـٰثَةِ ٱلَّذِينَ خُلِّفُوا۟ حَتَّىٰٓ إِذَا ضَاقَتْ عَلَيْهِمُ ٱلْأَرْضُ بِمَا رَحُبَتْ وَضَاقَتْ عَلَيْهِمْ أَنفُسُهُمْ وَظَنُّوٓا۟ أَن لَّا مَلْجَأَ مِنَ ٱللَّهِ إِلَّآ إِلَيْهِ ثُمَّ تَابَ عَلَيْهِمْ لِيَتُوبُوٓا۟ ۚ إِنَّ ٱللَّهَ هُوَ ٱلتَّوَّابُ ٱلرَّحِيمُ ﴿١١٨﴾

And [He also forgave] the three who were left behind [and regretted their error] to the point that the earth closed in on them in spite of its vastness and their souls confined them and they were certain that there is no refuge from Allah except in Him. Then He turned to them so they could repent. Indeed, Allah is the Accepting of repentance, the Merciful.
