Messenger of Allah ﷺ said: There is no trouble that comes to a believer except that it obliterates from his sins, even if it is the pricking of a thorn (Using translation from Muslim 2572e)   

أَنَّ رَسُولَ اللهِ ﷺ قَالَ «مَا مِنْ مُصِيبَةٍ يُصَابُ بِهَا الْمُؤْمِنُ إِلَّا كُفِّرَ حَتَّى الشَّوْكَةِ يُشَاكُهَا»  

A believer does not undergo (the trouble) of running a thorn or more than that when Allah effaces his sins. (Using translation from Muslim 2572c)   

قَالَ رَسُولُ اللهِ ﷺ «مَا يُصِيبُ الْمُؤْمِنَ مِنْ شَوْكَةٍ فَمَا فَوْقَهَا إِلَّا قَصَّ اللهُ عَنْهُ بِهَا خَطِيئَتَهُ»  

[Machine] 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»  

A believer does not receive (the trouble) of running a thorn or more than that but Allah elevates him in rank or effaces his sins because of that. (Using translation from Muslim 2572b)   

سَمِعْتُ رَسُولَ اللهِ ﷺ يَقُولُ «مَا مِنْ مُسْلِمٍ يُشَاكُ شَوْكَةً فَمَا فَوْقَهَا إِلَّا رَفَعَهُ اللهُ بِهَا دَرَجَةً وَحَطَّ عَنْهُ بِهَا خَطِيئَةً»  

[Machine] "O Messenger of Allah, what do we have regarding these illnesses?" He said, "Expiations (for sins)." He said, "Even if they are few?" He said, "Even if it is just a thorn."  

يَا رَسُولَ اللهِ مَا لَنَا فِي هَذِهِ الْأَمْرَاضِ؟ قَالَ «كَفَّارَاتٌ» قَالَ إِي وَإِنْ قَلَّتْ؟ قَالَ «وَلَوْ شَوْكَةً»
