Sahih Muslim , Book 7, Hadith 3197 (USC-MSA) ⓘ
Sa'd b. Abu Waqqas reported Allah's Messenger as saying: He who intends to do harm to the people of Medina, Allah would efface him just as water dissolves salt.
حَدَّثَنَا قُتَيْبَةُ بْنُ سَعِيدٍ، حَدَّثَنَا حَاتِمٌ، - يَعْنِي ابْنَ إِسْمَاعِيلَ - عَنْ عُمَرَ بْنِ نُبَيْهٍ، أَخْبَرَنِي دِينَارٌ الْقَرَّاظُ، قَالَ سَمِعْتُ سَعْدَ بْنَ أَبِي وَقَّاصٍ، يَقُولُ قَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم " مَنْ أَرَادَ أَهْلَ الْمَدِينَةِ بِسُوءٍ أَذَابَهُ اللَّهُ كَمَا يَذُوبُ الْمِلْحُ فِي الْمَاءِ " .
