“He (Allah) is the One, deserving that mankind should be afraid of, and should be dutiful to Him, and should not take any Ilah (god) along with Him, and He is the One Who forgives (sins).” Then he said: “Allah says: ‘I am the One Who deserves to be feared, so no other god should be appointed alongside Me. Whoever avoids appointing another god alongside Me, I am the One Who should forgive him.”

Another chain reports a similar hadith.
Sunan Ibn Majah Book 37, Hadith 200
← Previous Hadith “The Messenger of Allah (ﷺ) said: “No one will enter Hell except one who is doomed.” It was said: “O Messenger of Allah, who is the one who is doomed?” He said: “The one who never does any act of obedience (towards Allah) and who never omitted any act of sin.”

Sunan Ibn Majah Book 37, Hadith 199 Next Hadith → “A man from my nation will be called before all of creation on the Day of Resurrection, and ninety-nine scrolls will be spread out for him, each one extending as far as the eye can see. Then Allah will say: “Do you deny anything of this?” He will say: “No, O Lord.” He will say: “Have My recording scribes been unfair to you?” Then He will say: “Apart from that, do you have any good deeds?” The man will be terrified and will say: “No.” (Allah) will say: “Indeed, you have good deeds with Us, and you will not be treated unjustly this Day.” Then a card will be brought out on which is written Ash-hadu an la ilaha illallah wa anna Muhammadan ‘abduhu wa rasuluhu (I bear witness that none has the right to be worshipped but Allah, and that Muhammad is His slave and Messenger). He will say: “O Lord, what is this card compared with these scrolls?” He will say: “You will not be treated unjustly.” Then the scrolls will be placed in one side of the Balance and the card in the other. The scrolls will go up (i.e., be light) and the card will go down (i.e., will weigh heavily).”
