Hadith 1
The Book on Jana''iz (Funerals)
Abu Sa'eed Al-Khudri (may Allah be pleased with him) narrated that:
The Messenger of Allah said: "Nothing afflicts the believer, whether fatigue, grief, disease - even a worry that concerns him - except that by it, Allah removes something from his bad deeds."
حَدَّثَنَا سُفْيَانُ بْنُ وَكِيعٍ، حَدَّثَنَا أَبِي، عَنْ أُسَامَةَ بْنِ زَيْدٍ، عَنْ مُحَمَّدِ بْنِ عَمْرِو بْنِ عَطَاءٍ، عَنْ عَطَاءِ بْنِ يَسَارٍ، عَنْ أَبِي سَعِيدٍ الْخُدْرِيِّ، رضى الله عنه قَالَ قَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم
مَا مِنْ شَيْءٍ يُصِيبُ الْمُؤْمِنَ مِنْ نَصَبٍ وَلاَ حَزَنٍ وَلاَ وَصَبٍ حَتَّى الْهَمُّ يَهُمُّهُ إِلاَّ يُكَفِّرُ اللَّهُ بِهِ عَنْهُ سَيِّئَاتِهِ
