[Machine] I heard from the Messenger of Allah ﷺ a hadith that Allah benefited me with as He pleased to benefit me with, and when someone else narrated to me, I would make him swear an oath, and if he swore to me, I would believe him. Abu Bakr narrated to me and Abu Bakr is truthful. He said, "I heard the Messenger of Allah ﷺ saying, 'There is no servant who commits a sin, then gets up and performs ablution and perfects it, then prays two Rak'ahs and seeks forgiveness from Allah, except that Allah forgives him.'" Abu Dawood narrated to us, Ahmad bin Sulaiman narrated to us, Ja'far bin 'Awn narrated to us, Mus'ab narrated to us, and Harun bin Ishaq narrated to me from Muhammad from Mus'ab from 'Uthman bin al-Mughirah from Ali bin Rabiah from Asma bin Hakam from Ali similar to this. And he said regarding it, Abu Bakr narrated to me and Abu Bakr is truthful, 'Verily, there is no man who commits...' and so on.  

سَمِعْتُ مِنْ رَسُولِ اللهِ ﷺ حَدِيثًا نَفَعَنِي اللهُ بِمَا شَاءَ أَنْ يَنْفَعَنِي بِهِ وَإِذَا حَدَّثَنِي غَيْرُهُ اسْتَحْلَفْتُهُ فَإِذَا حَلَفَ لِي صَدَّقْتُهُ فَحَدَّثَنِي أَبُو بَكْرٍ وَصَدَقَ أَبُو بَكْرٍ قَالَ سَمِعْتُ رَسُولَ اللهِ ﷺ يَقُولُ «لَيْسَ مِنْ عَبْدٍ يُذْنِبُ ذَنْبًا فَيَقُومُ فَيَتَوَضَّأُ فَيُحْسِنُ الْوُضُوءَ ثُمَّ يُصَلِّي رَكْعَتَيْنِ ثُمَّ يَسْتَغْفِرُ اللهَ إِلَّا غَفَرَ اللهُ لَهُ» 10176 أَخْبَرَنَا أَحْمَدُ بْنُ سُلَيْمَانَ حَدَّثَنَا جَعْفَرُ بْنُ عَوْنٍ حَدَّثَنَا مِسْعَرٌ وَأَخْبَرَنَا هَارُونُ بْنُ إِسْحَاقَ حَدَّثَنِي مُحَمَّدٌ عَنْ مِسْعَرٍ عَنْ عُثْمَانَ بْنِ الْمُغِيرَةِ عَنْ عَلِيِّ بْنِ رَبِيعَةَ عَنْ أَسْمَاءَ بْنِ الْحَكَمِ عَنْ عَلِيٍّ مِثْلَهُ وَقَالَ فِيهِ حَدَّثَنِي أَبُو بَكْرٍ وَصَدَقَ أَبُو بَكْرٍ «إِنَّهُ لَيْسَ مِنْ رَجُلٍ يُذْنِبُ» نَحْوَهُ  

[Machine] On the authority of the Messenger of Allah ﷺ, I swore an oath to his companion, and when he swore, I believed him. Abu Bakr narrated to me and Abu Bakr spoke the truth when he said, "There is no servant who commits a sin, then performs ablution and prays two units of voluntary prayer, and seeks forgiveness from Allah, except that Allah forgives him."  

عَنْ رَسُولِ اللهِ ﷺ حَدِيثًا اسْتَحْلَفْتُ صَاحِبَهُ فَإِذَا حَلَفَ صَدَّقْتُهُ وَحَدَّثَنِي أَبُو بَكْرٍ وَصَدَقَ أَبُو بَكْرٍ أَنَّهُ قَالَ «لَيْسَ مِنْ عَبْدٍ يُذْنِبُ ذَنْبًا فَيَتَوَضَّأُ وَيُصَلِّي رَكْعَتَيْنِ ثُمَّ يَسْتَغْفِرُ اللهَ إِلَّا غَفَرَ لَهُ»  

I heard ‘Ali say: If I heard a hadeeth from the Messenger of Allah ﷺ, Allah benefitted me as He willed thereby. If someone else told me something from him I would ask him to swear, and if he swore I would believe him. Abu Bakr told me - and Abu Bakr told the truth - that he heard the Prophet ﷺ say: ʿThere is no believer who commits a sin, then does wudooʿ and does it well and prays two rak'ahs and asks Allah, may He be glorified and exalted, for forgiveness but Allah will forgive him.ʿ Then he recited the verse: ʿAnd those who, when they have committed Fahishah (illegal sexual intercourse) or wronged themselves...ʿ (Al ‘Imran 3:135). (Using translation from Aḥmad 56)   

سَمِعْتُ مِنْ رَسُولِ اللهِ ﷺ حَدِيثًا نَفَعَنِي اللهُ بِمَا شَاءَ أَنْ يَنْفَعَنِي وَإِذَا حَدَّثَنِي رَجُلٌ مِنْ أَصْحَابِهِ اسْتَحْلَفْتُهُ فَإِذَا حَلَفَ لِي صَدَّقْتُهُ وَإِنَّهُ حَدَّثَنِي أَبُو بَكْرٍ وَصَدَقَ أَبُو بَكْرٍ قَالَ سَمِعْتُ رَسُولَ اللهِ ﷺ يَقُولُ «مَا مِنْ رَجُلٍ مُؤْمِنٍ يُذْنِبُ ذَنْبًا ثُمَّ يَقُومُ فَيَتَطَهَّرُ فَيُحْسِنُ الطُّهُورَ ثُمَّ يَسْتَغْفِرُ اللهَ إِلَّا غَفَرَ اللهُ لَهُ» ثُمَّ قَرَأَ الْآيَةَ {وَالَّذِينَ إِذَا فَعَلُوا فَاحِشَةً أَوْ ظَلَمُوا أَنْفُسَهُمُ} [آل عمران 135] إِلَى آخِرِ الْآيَةِ  

the Messenger of Allah said: “Verily, when the slave (of Allah) commits a sin, a black spot appears on his heart. When he refrains from it, seeks forgiveness and repents, his heart is polished clean. But if he returns, it increases until it covers his entire heart. And that is the ‘Ran’ which Allah mentioned: ‘Nay, but on their hearts is the Ran which they used to earn.’” (Using translation from Tirmidhī 3334)   

عَنْ رَسُولِ اللهِ ﷺ قَالَ إنَّ الْعَبْدَ إِذَا أَخْطَأَ خَطِيئَةً نُكِتَ فِي قَلْبِهِ نُكْتَةٌ فَإِنْ هُوَ نَزَعَ وَاسْتَغْفَرَ وَتَابَ صُقِلَتْ وَإِنْ عَادَ زِيدَ فِيهَا حَتَّى تُغْلِقَ قَلْبَهُ فَهُوَ الرَّانُ الَّذِي ذَكَرَ اللهُ {كَلَّا بَلْ رَانَ عَلَى قُلُوبِهِمْ مَا كَانُوا يَكْسِبُونَ} [المطففين 14]
