Hadith 8:81
He reported God's Messenger as saying, “If you were to sell something to your brother and it was smitten by blight it would not be allowable for you to take anything from him. Why should you take your brother's property unjustly?” Muslim transmitted it.
وَعَنْهُ قَالَ: قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ: «لَوْ بِعْتَ مِنْ أَخِيكَ ثَمَرًا فَأَصَابَتْهُ جَائِحَةٌ فَلَا يَحِلُّ لَكَ أَنْ تَأْخُذَ مِنْهُ شَيْئًا بِمَ تَأْخُذُ مَالَ أَخِيكَ بِغَيْرِ حقٍ؟» . رَوَاهُ مُسلم
