Importance of sin and forgiveness in the Plan of Allah

The Messenger of Allah ﷺ said, "By Him in Whose Hand is my life, if you were not to commit sins, Allah would do away with you and ˹replace you by˺ bringing a nation who would commit sins and seek forgiveness from Allah, and He would then forgive them."  

قَالَ رَسُولُ اللَّهِ ﷺ: «وَالَّذِي نَفْسِي بِيَدِهِ لَوْ لَمْ تُذْنِبُوا لَذَهَبَ اللَّهُ بِكُمْ وَلَجَاءَ بِقَوْمٍ يُذْنِبُونَ فَيَسْتَغْفِرُونَ اللَّهَ فَيَغْفِرُ لَهُمْ۔»  

By Him in Whose Hand is my life, if you were not to commit sin, Allah would sweep you out of existence and He would replace (you by) those people who would commit sin and seek forgiveness from Allah, and He would have pardoned them. (Using translation from Muslim 2749)  

قَالَ رَسُولُ اللهِ ﷺ وَالَّذِي نَفْسِي بِيَدِهِ لَوْ لَمْ تُذْنِبُوا لَذَهَبَ اللهُ بِكُمْ وَلَجَاءَ بِقَوْمٍ يُذْنِبُونَ فَيَسْتَغْفِرُونَ اللهَ فَيَغْفِرُ لَهُمْ  

[Machine] I heard the Messenger of Allah ﷺ say, "If it were not for the fact that you commit sins, Allah would have created a creation that commits sins and He would forgive them."  

سَمِعْتُ رَسُولَ اللهِ ﷺ يَقُولُ «لَوْلَا أَنَّكُمْ تُذْنِبُونَ لَخَلَقَ اللهُ خَلْقًا يُذْنِبُونَ يَغْفِرُ لَهُمْ»  

[Machine] The Messenger of Allah ﷺ said, "If you did not commit sins, Allah would replace you with people who would commit sins and seek His forgiveness."  

قَالَ رَسُولُ اللهِ ﷺ «لَوْ لَمْ تُذْنِبُوا لَجَاءَ اللهُ بِقَوْمٍ يُذْنِبُونَ فَيَغْفِرُ لَهُمْ»  

"لَوْ لَمْ يُذْنبُوا لَجَاءَ الله بقَوْمٍ يُذْنبُونَ فَيَغْفرُ لَهُمْ".  

"لَوْ لَمْ يُذْنِبُوا لَخَلَقَ الله خَلقًا يُذْنِبُونَ ثُمَّ يَغْفِرُ لَهُمْ".  

"لَوْلا أنَّكُمْ تُذْنِبُون لَجَاءَ الله بِقَوْمٍ يُذْنِبُونَ فَيَسْتَغْفِرُونَ الله فَيَغْفرُ لهم".  

"عَنْ حُذَيْفَةَ قَالَ: لَوْ لَمْ يُذْنِبُوا أَوْ يُخْطِئُوا لَجَاءَ الله بِقَوْمٍ يُذْنِبُونَ وَيُخْطِئُونَ يَغْفِرُ لَهُمْ يَوْمَ الْقِيامَةِ".  

"كَفَّارَةُ الذَّنْبِ النَّدَامَةُ، وَلَوْ لَمْ تُذْنِبُوا لأَتَى الله بِقَوْمٍ يُذْنِبُونَ فَيَغْفِرُ لَهُمْ (*) ".
