Tirmidhi

Explanation:
1:
The Prophet (sallallahu alayhi wa sallam) would seek forgiveness (istighfar) seventy times in a day, and according to some narrations, one hundred times. Because of this, he was called "the Prophet of Repentance" (Nabi at-Tawbah).

Hadith Commentary:
(1)
Hafiz Ibn Hajar rahimahullah has written, quoting Muhallab:
The majority of scholars are agreed that when a free man accuses a slave of adultery, the prescribed punishment (hadd) will not be carried out upon him, because there is a hadith stating that the one who makes such an accusation will be punished and flogged on the Day of Resurrection.
If the prescribed punishment (hadd) were to be applied in this world, it would have been mentioned in the hadith just as the punishment of the Hereafter is mentioned.

(2)
Hafiz Ibn Hajar rahimahullah says that the claim of consensus (ijma‘) is questionable, because Hazrat Nafi‘ narrates that Hazrat Ibn ‘Umar radi Allahu anhuma held the opinion that the prescribed punishment (hadd) should be carried out upon one who accuses an umm walad (a slave woman who has borne her master’s child) of adultery.
(Fath al-Bari: 12/229)

Hadith Commentary: Benefits and Issues: If a master accuses his slave of adultery, while he has no proof of it, then, out of respect and honor for the slave’s right to freedom, by unanimous agreement, the prescribed punishment (hadd) will not be established against him in this world, whether he is a complete slave, a mukatab (contracted for manumission), a mudabbar (freedom promised after the master's death), or an umm walad (a slave woman who has borne her master’s child). However, on the Day of Judgment, he will be deserving of the prescribed punishment. But if someone accuses another person’s umm walad, then according to Ibn Umar, Hasan al-Basri, and the Zahiri scholars, the prescribed punishment will be established against him. If he accuses his own umm walad, then Hasan al-Basri’s position is also that there is no prescribed punishment. Similarly, in the case of accusing another person’s slave, there is also no prescribed punishment; rather, there is discretionary punishment (ta’zir) and reprimand, and in the Hereafter, there will be accountability.

Benefits and Issues:
One of the attributes of the Messenger of Allah (sallallahu alayhi wa sallam) is "Nabi al-Tawbah" (the Prophet of Repentance), the meaning of which is that the repentance (tawbah) of this Ummah is accepted through remorse and words.
Whereas in previous communities, at times, repentance was accepted only by killing themselves.
Another meaning has also been written,
that by this is meant faith (iman) and action,
when a person has turned away from disbelief (kufr) and transgression (fisq).

Takhrij:
«أخرجه البخاري، الحدود، باب قذف العبيد، حديث:6858، ومسلم، الأيمان، باب التغليظ علي من قذف مملوكه بالزني، حديث:1660.»©Explanation:
From this hadith, it is understood that if an owner accuses his slave falsely, then there is no prescribed punishment (hadd) for him in this world; Allah, Lord of all the worlds, will punish him on the Day of Resurrection.
And if the accusation is true, then the owner will be absolved of responsibility, and the slave will be punished for the crime.
