Abu Huraira reported: The Prophet, peace and blessings be upon him, ascended the pulpit and he said, “Amin, amin, amin.” It was said, “O Messenger of Allah, you ascended the pulpit and said amin, amin, amin.” The Prophet said, “Verily, Gabriel came to me and he said: Whoever reaches the month of Ramadan and he is not forgiven, then he will enter Hellfire and Allah will cast him far away, so say amin. I said amin. Whoever sees his parents in their old age, one or both of them, and he does not honor them and he dies, then he will enter Hellfire and Allah will cast him far away, so say amin. I said amin. Whoever has your name mentioned in his presence and he does not send blessings upon you and he dies, then he will enter Hellfire and Allah will cast him far away, so say amin. I said amin.”

I heard the Messenger of Allah (ﷺ) say: Allah the Almighty said: O son of Adam, so long as you call upon Me and ask of Me, I shall forgive you for what you have done, and I shall not mind. O son of Adam, were your sins to reach the clouds of the sky and were you then to ask forgiveness of Me, I would forgive you. O son of Adam, were you to come to Me with sins nearly as great as the earth and were you then to face Me, ascribing no partner to Me, I would bring you forgiveness nearly as great as it. It was related by at-Tirmidhi (also by Ahmad ibn Hanbal). Its chain of authorities is sound.
عَنْ أَنَسٍ رَضِيَ اللهُ عَنْهُ ، قَالَ : سَمِعْتُ رَسُولَ اللهِ صَلَّى الله عَلَيْهِ وَ سَلَّمَ ، يَقُولُ : قَالَ اللهُ تَعَالَى : يَا ابْنَ ادَمَ ، إِنَّكَ مَا دَعَوْتََنِي وَرَجَوْتَنِي ، غَفَرْتُ لَكَ عَلَى مَا كَانَ مِنْكَ وَلَا أُبالِي . يا ابْنَ ادَمَ :لَوْ بَلَغَتْ ذُنُوبُكَ عَنانَ السَّماءِ ثُم َّ اسْتَغْفَرْتَني ، غَفَرْتُ لَكَ . يَا ابْنَ ادَمَ : إِنَّكَ لَوْ أَتَيْتَنِي بِقُرَابِ الأَرْضِ خَطَايا ثُمَّ لَقِيتَني لَا تُشْرِكُ بِي شَيْأً ، لَأَتيْتُكَ بِقُرَابِها مَغْفِرَةً رواهُ الترمذي (وكذلك أحمد) وسنده حسن
