"I heard 'Ali saying: 'Indeed I am a man who, when I hear a Hadith from the Messenger of Allah ﷺ, then Allah causes me to benefit from it as much as He wills for me to benefit from it. When a man among his Companions narrates to me I ask him to swear an oath to me, about it, and when he swears an oath to me I trust him. And Abu Bakr narrated to me - and Abu Bakr told the truth - he said: "I heard the Messenger of Allah ﷺ saying: 'There is no man who commits a sin, then stands for purification, then performs Salat, then seeks forgiveness from Allah, except that Allah forgives him.' Then he recites this Ayah: Those who, when they have committed Fahishah or wronged themselves with evil, remember Allah... (3:135) until the end of the Ayah."
سَمِعْتُ عَلِيًّا يَقُولُ إِنِّي كُنْتُ رَجُلاً إِذَا سَمِعْتُ مِنْ رَسُولِ اللَّهِ ﷺ حَدِيثًا نَفَعَنِي اللَّهُ مِنْهُ بِمَا شَاءَ أَنْ يَنْفَعَنِي وَإِذَا حَدَّثَنِي رَجُلٌ مِنْ أَصْحَابِهِ اسْتَحْلَفْتُهُ فَإِذَا حَلَفَ لِي صَدَّقْتُهُ وَإِنَّهُ حَدَّثَنِي أَبُو بَكْرٍ وَصَدَقَ أَبُو بَكْرٍ قَالَ سَمِعْتُ رَسُولَ اللَّهِ ﷺ يَقُولُ مَا مِنْ رَجُلٍ يُذْنِبُ ذَنْبًا ثُمَّ يَقُومُ فَيَتَطَهَّرُ ثُمَّ يُصَلِّي ثُمَّ يَسْتَغْفِرُ اللَّهَ إِلاَّ غَفَرَ لَهُ ثُمَّ قَرَأَ هَذِهِ الآيَةَ (وَالَّذِينَ إِذَا فَعَلُوا فَاحِشَةً أَوْ ظَلَمُوا أَنْفُسَهُمْ ذَكَرُوا اللَّهَ فَاسْتَغْفَرُوا ) إِلَى آخِرِ الآيَةِ
