If you were not to commit sins, Allah would have swept you out of existence and would have replaced you by another people who have committed sin, and then asked forgiveness from Allah, and He would have granted them pardon.
[Muslim]
Ibn Abbas RA said: “I never saw the Messenger of Allah ﷺ so keen to fast on any day and give it priority over any other than this day, the day of Ashura and this month (Ramadan)."
[Bukhari]
Allah is more pleased with the repentance of His slave than anyone of you is pleased with finding his camel which he had lost in the desert
[Hadith Bukhari]
