I used to conceal from you a thing which I heard from Messenger of Allah ﷺ and I heard Messenger of Allah ﷺ as saying: Had you not committed sins, Allah would have brought into existence a creation that would have committed sin (and Allah) would have forgiven them.  

أَنَّهُ قَالَ حِينَ حَضَرَتْهُ الْوَفَاةُ كُنْتُ كَتَمْتُ عَنْكُمْ شَيْئًا سَمِعْتُهُ مِنْ رَسُولِ اللَّهِ ﷺ سَمِعْتُ رَسُولَ اللَّهِ ﷺ يَقُولُ لَوْلاَ أَنَّكُمْ تُذْنِبُونَ لَخَلَقَ اللَّهُ خَلْقًا يُذْنِبُونَ يَغْفِرُ 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»
