No trouble comes to a believer even if it is the pricking of a thorn that it becomes (the means) whereby his sins are effaced or his sins are obliterated. Yazid says: He does not know which word 'Urwa said (whether he said Qussa or Kuffira).

عَنْ عَائِشَةَ زَوْجِ النَّبِيِّ ﷺ أَنَّ رَسُولَ اللَّهِ ﷺ قَالَ لاَ يُصِيبُ الْمُؤْمِنَ مِنْ مُصِيبَةٍ حَتَّى الشَّوْكَةِ إِلاَّ قُصَّ بِهَا مِنْ خَطَايَاهُ أَوْ كُفِّرَ بِهَا مِنْ خَطَايَاهُ لاَ يَدْرِي يَزِيدُ أَيَّتُهُمَا قَالَ عُرْوَةُ

Yahya related to me from Malik from Yazid ibn Khusayfa that Urwa ibn az-Zubayr said that he heard A'isha, the wife of the Prophet ﷺ say, "The Messenger of Allah ﷺ said, 'When a mumin is afflicted by something, even a thorn, it removes (or effaces) his wrong actions.' " Yazid did not know which of them Urwa said.

أَنَّهُ قَالَ سَمِعْتُ عَائِشَةَ زَوْجَ النَّبِيِّ ﷺ تَقُولُ قَالَ رَسُولُ اللَّهِ ﷺ لاَ يُصِيبُ الْمُؤْمِنَ مِنْ مُصِيبَةٍ حَتَّى الشَّوْكَةُ إِلاَّ قُصَّ بِهَا أَوْ كُفِّرَ بِهَا مِنْ خَطَايَاهُ لاَ يَدْرِي يَزِيدُ أَيَّهُمَا قَالَ عُرْوَةُ

[AI] The Messenger of Allah ﷺ said, "No fatigue, illness, anxiety, sorrow, harm, or distress befalls a believer, even if it be the prick he receives from a thorn, except that Allah expiates some of his sins thereby."

عَنْ رَسُولِ اللهِ ﷺ قَالَ «مَا يُصِيبُ الْمُؤْمِنَ مِنْ وَصَبٍ حَتَّى الشَّوْكَةِ إِلَّا قَصَّ اللهُ بِهَا أَوْ كَفَّرَ بِهَا مِنْ خَطَايَاهُ»
