Does Allah forgive abundant sins and pardon them, and save the one who committed them from the torment of the grave and the Hereafter if he repents with sincere repentance?

Prophetic traditions mention that Allah's mercy is vast and His forgiveness is immense. Whoever supplicates to Allah and hopes in Him, He forgives his sins no matter how great they are. Whoever seeks His forgiveness, He forgives him even if his sins reach the clouds of the sky. And whoever comes to Him with sins filling the earth, yet has not associated anything with Him, Allah will come to him with forgiveness filling the earth. This is also narrated in the story of a man from the Children of Israel who killed ninety-nine souls, then completed a hundred, but he repented with sincere repentance, so Allah forgave him.
