مَا يُصِيبُ الْمُسْلِمَ مِنْ نَصَبٍ وَلَا وَصَبٍ وَلَا هَمٍّ وَلَا حَزَنٍ وَلَا أَذًى وَلَا غَمٍّ حَتَّى الشَّوْكَةِ يُشَاكُهَا إِلَّا كَفَّرَ اللَّهُ بِهَا مِنْ خَطَايَاهُ
Ma yusibu al-Muslima min nasabin wa la wasabin wa la hammin wa la hazanin wa la adhan wa la ghammin hatta ash-shawkati yushakuha illa kaffarAllahu biha min khatayah
No fatigue, illness, anxiety, sadness, harm, or distress befalls a Muslim — even the prick of a thorn — except that Allah expiates some of his sins because of it.
Not a du'a but a promise — and one of the most comforting hadiths for the sick. Six types of suffering are listed, from serious illness down to a tiny thorn prick. Nothing is wasted. Every ache, every worry, every moment of discomfort is converting sins into expiation. The math is always in your favor: temporary pain for permanent forgiveness. The believer who is sick and patient is winning on two fronts.
