(14) باب ثَوَابِ الْمُؤْمِنِ فِيمَا يُصِيبُهُ مِنْ مَرَضٍ أَوْ حُزْنٍ أَوْ نَحْوِ ذَلِكَ حَتَّى الشَّوْكَةِ يُش
'A'isha reported:
I heard Allah's Messenger (ﷺ) as saying: There is nothing (in the form of trouble) that comes to a believer even if it is the pricking of a thorn that there is decreed for him by Allah good or his sins are obliterated.
