[Machine] I heard Salman al-Farsi in Isfahan say, "A servant does not believe until he knows that what befalls him could not have missed him, and what misses him could not have befallen him."  

سَمِعْتُ سَلْمَانَ الْفَارِسِيَّ بأَصْبَهَانَ يَقُولُ «لَا يُؤْمِنُ عَبْدٌ حَتَّى يَعْلَمَ أَنَّ مَا أَصَابَهُ لَمْ يَكُنْ لِيُخْطِئَهُ وَمَا أَخْطَأَهُ لَمْ يَكُنْ لِيُصِيبَهُ»  

[Machine] The Prophet ﷺ said, "Whoever says, 'O Allah, I bear witness that You are Allah, and I bear witness that Your angels and the bearers of Your Throne and the heavens and all that is in them and the earths and all that is in them bear witness that there is no god but You, and I disbelieve in anyone who denies this from the past and the future. And I bear witness that Muhammad is Your servant and Your Messenger.' Whoever says it once, a third of his sins will be forgiven. Whoever says it twice, two-thirds of his sins will be forgiven. Whoever says it three times will be completely forgiven of all sins."  

قَالَ النَّبِيُّ ﷺ مَنْ قَالَ اللهُمَّ إِنِّي أُشْهِدُكَ وَأُشْهِدُ مَلَائِكَتَكَ وَحَمَلَةَ الْعَرْشِ وَالسَّمَاوَاتِ وَمَنْ فِيهِنَّ وَالْأَرَضِينَ وَمَنْ فِيهِنَّ وَأُشْهِدُ جَمِيعَ خَلَقِكَ بِأَنَّكَ اللهُ لَا إِلَهَ إِلَّا أَنْتَ وَأُكَفِّرُ مَنْ أَبَى ذَلِكَ مِنَ الْأَوَّلِينَ وَالْآخِرِينَ وَأَشْهَدُ أَنَّ مُحَمَّدًا عَبْدُكَ وَرَسُولُكَ مَنْ قَالَهَا مَرَّةً عُتِقَ ثُلُثُهُ مِنَ النَّارِ وَمَنْ قَالَهَا مَرَّتَيْنِ عُتِقَ ثُلُثَاهُ مِنَ النَّارِ وَمَنْ قَالَهَا ثَلَاثًا عُتِقَ مِنَ النَّارِ
