´It was narrated from Ali that the Messenger of Allah (ﷺ) said:` “Whoever commits a sin in this world and is punished for it, Allah (STW) is too just to repeat the punishment for his slave (in the hereafter). And whoever commits a sin in this world and Allah conceals him, Allah is too generous to go back to something that He has pardoned.”
Hadith Takhrij«سنن الترمذی/الإیمان 11 ( 2626 ) ، ( تحفة الأشراف : 10313 ) ، وقد أخرجہ : مسند احمد ( 1/99 ، 159 ) ( ضعیف ) » ( سند میں حجاج بن محمد مصیصی ہیں ، جو بغداد آنے کے بعد اختلاط کا شکار ہو گئے ، اور ہارون بن عبد اللہ الحمال ان کے شاگرد بغدادی ہیں ، اس لئے ان کی روایت حجاج سے اختلاط کی وجہ سے ضعیف ہے )
1؎ : From the preceding authentic hadiths, it is understood that the implementation of the prescribed punishments (hudud) becomes an expiation for the sin; this is the view of the majority of the scholars (muhhaqiqin). However, some scholars have said that the prescribed punishment does not absolve the sin, rather repentance (tawbah) is required for the forgiveness of the sin, and they have several evidences for this:
Firstly, in the case of banditry (hirabah), Allah the Exalted has said: «ذلك لهم خزي في الدنيا ولهم في الآخرة عذاب عظيم» (Surah al-Ma'idah: 33), meaning, "The prescribed punishment is a disgrace in this world, and in the Hereafter they will have a painful punishment."
Secondly, in one narration it is mentioned: "I do not know whether the prescribed punishments are an expiation or not."
Thirdly, as has been mentioned in the hadith of Abu Umayyah al-Makhzumi, when the hand of the thief was cut off, the Prophet (sallallahu alayhi wa sallam) said to him: "Seek forgiveness from Allah and repent."
´Narrated Ali bin Abu Talib:` that the Prophet (ﷺ) said: "Whoever is penalized (for a crime) then his punishment has been hastened for him in the world, for Allah is more just than to double the punishment upon His slave in the Hereafter. And whoever does a punishable act and then Allah covers it for him and forgives him, then Allah is more kind than to recount something which He has already forgiven."

Commentary: Note: (In the chain of narration, although Hajjaj ibn Muhammad al-Misisi is a trustworthy (thiqa) narrator, he became subject to confusion (ikhtilat) after coming to Baghdad shortly before his death. And Abu Ishaq al-Sabi'i is trustworthy (thiqa) but a mudallis (one who practices tadlis) and a narrator who became confused (mukhtalit), and this narration is with 'an'anah (i.e., he narrates with the word "from").)
