Please assess the authenticity of the following hadith.
In particular, this part:
“He said:
‘I said this only because I wanted to explain it to you; but I was overcome by a sudden tightness in my breath, which prevented me from continuing.’”
It is narrated that once, in Kufa, the Commander of the Faithful, peace be upon him, mounted the pulpit and said:
“O people, sins are of three kinds.” Then he fell silent.
Ḥabba al-ʿUranī said:
“O Commander of the Faithful, you said that sins are of three kinds, and then you fell silent!”
He replied:
“I said this only because I wanted to explain it to you; but I was overcome by a sudden tightness in my breath, which prevented me from continuing. Yes, sins are of three kinds: a sin that is forgiven; a sin that is not forgiven; and a sin for whose perpetrator we both hope and fear.”
He said:
“O Commander of the Faithful, explain these to us!”
He replied:
“As for the sin that is forgiven, it is when God punishes a servant in this world for his sin. God is too forbearing and too generous to punish a servant twice.
“As for the sin that is not forgiven, it is the wrong people do to one another. When God, blessed and exalted is He, appears to His servants [on the Day of Resurrection], He will swear by Himself: ‘By My might and majesty, I will not overlook any wrongdoer’s injustice, even if it was a hand striking another hand, or merely a touch of the hand, or even a goat butting a ewe with its horns.’ The wrongs people have done to one another will then be fully redressed, until no one remains with a claim of injustice against anyone else. Only then will they be raised for the reckoning.
“As for the third kind, it is a sin that God has concealed from His creatures and for which He has granted the person repentance. Such a person comes fearing his sin and hoping in his Lord. We, too, regard him as he regards himself: we hope for mercy for him and fear that he may be punished.”

علی بن إبراهیم عن أبیه عن عبد الرحمن بن حماد عن بعض أصحابه رفعه قال:
صعد أمیر المؤمنین ع بالکوفه المنبر فحمد الله و أثنى علیه ثم قال: أیها الناس إن الذنوب ثلاثه. ثم أمسک.
فقال له حبه العرنی: یا أمیر المؤمنین قلت الذنوب ثلاثه ثم أمسکت؟!
فقال ما ذکرتها إلا و أنا أرید أن أفسرها و لکن عرض لی بهر حال بینی و بین الکلام. نعم الذنوب ثلاثه فذنب مغفور و ذنب غیر مغفور و ذنب نرجو لصاحبه و نخاف علیه.
قال یا أمیر المؤمنین فبینها لنا.
قال نعم أما الذنب المغفور فعبد عاقبه الله على ذنبه فی الدنیا فالله أحلم و أکرم من أن یعاقب عبده مرتین و أما الذنب الذی لا یغفر فمظالم العباد بعضهم لبعض إن الله تبارک و تعالى إذا برز لخلقه أقسم قسما على نفسه فقال و عزتی و جلالی لا یجوزنی ظلم ظالم و لو کف بکف و لو مسحه بکف و لو نطحه ما بین القرناء إلى الجماء فیقتص للعباد بعضهم من بعض حتى لا تبقى لأحد على أحد مظلمه ثم یبعثهم للحساب و أما الذنب الثالث فذنب ستره الله على خلقه و رزقه التوبه منه فأصبح خائفا من ذنبه راجیا لربه فنحن له کما هو لنفسه نرجو له الرحمه و نخاف علیه العذاب.
