The Book of Virtue, Enjoining Good Manners, and Joining of the Ties of Kinship
Ṣaḥīḥ Muslim 6561
مَا مِنْ مُسْلِمٍ يُشَاكُ شَوْكَةً فَمَا فَوْقَهَا إِلاَّ كُتِبَتْ لَهُ بِهَا دَرَجَةٌ وَمُحِيَتْ عَنْهُ بِهَا خَطِيئَةٌ
mā min muslimin yushāku shawkatan famā fawqahā illā kutibat lah bihā darajatun wamuḥiyat ʿanhu bihā khaṭīʾatun

The full narration
Aswad reported that some young men from the Quraish visited 'A'isha as she was in Mina and they were laughing. She said:What makes you laugh? They said: Such and such person stumbled against the rope of the tent and he was about to break his neck or lose his eyes. She said: Don't laugh for I heard Allah's Messenger (ﷺ) as saying: If a Muslim runs a thorn or (gets into trouble) severe than this, there is assured for him (a higher) rank and his sins are obliterated
