Sunan Ibn Majah, Volume 3, Book 21, Hadith 2693 (DarusSalam) ⓘ
Abu Darda said: “I heard the Messenger of Allah say: 'There is no man who suffers some (injury) on his body and forgives (the perpetrator), but Allah (SWT) will raise him one degree in status thereby, or erase from him one sin.'My own ears heard it and my heart memorized it.”
حَدَّثَنَا عَلِيُّ بْنُ مُحَمَّدٍ، حَدَّثَنَا وَكِيعٌ، عَنْ يُونُسَ بْنِ أَبِي إِسْحَاقَ، عَنْ أَبِي السَّفَرِ، قَالَ قَالَ أَبُو الدَّرْدَاءِ سَمِعْتُ رَسُولَ اللَّهِ صلى الله عليه وسلم يَقُولُ " مَا مِنْ رَجُلٍ يُصَابُ بِشَىْءٍ مِنْ جَسَدِهِ فَيَتَصَدَّقُ بِهِ إِلاَّ رَفَعَهُ اللَّهُ بِهِ دَرَجَةً أَوْ حَطَّ عَنْهُ بِهِ خَطِيئَةً " . سَمِعَتْهُ أُذُنَاىَ وَوَعَاهُ قَلْبِي .
